im not sure how clearly your phrasing your question, but when dealing with circuits potential difference (voltage) is max, and at the positive terminal its zero. it decreases as you go around the circuit. hope this helps

How does a graph line with a steeper slpoe compare to one with a shallower slope?
Above the x axis, a steeper slope means more positive and therefore a faster rate of change of y with respect to x. This rate increases as the slope goes more and more away from the x axis. Below the x axis a steeper slope means more negative and therefore a faster rate of change of y with respect to x in the negative side. This rate increases as the slope goes more and more away from the x axis. For a distance vs. time graph. A steep positive slope means higher velocity. A steeper negative slope means higher velocity in the direction opposite to motion (declaration in a way).
Why arent all integrals of root x 0 as the graph is symmetrical about the x-axis?
The integral of a function, with respect to x, may be regarded as the area between the function and the x-axis. However, the calculated area - using integration - is positive when the graph is above the x-axis and negative when the graph is below. For a function which is partly above the x-axis and partly below, it is necessary to partition it into sub-domains over which it is positive and other sub-domains where it is negative. All the parts where it is above the x-axis are then integrated as normal. Where the graph is negative, the integral is calculated as normal but then the sign of the result must be changed before adding the results to the "positive" areas.
What is the combination of real numbers in math?
It depends on the combination. Real numbers are closed with respect to arithmetical operations (+, -, *, /), as well as integer powers (exponents). So a combination of real numbers using any of these operators will yield a real number. But the set is not closed with respect to some fractional powers - for example, the square root of a negative number is not real.It depends on the combination.

How can you get negative voltage?
Your question should read "How do you get a negative potential?", for the reasons explained below.The term, 'voltage', is another word for 'potential difference'. The terms 'positive' and 'negative', when applied to a potential difference or voltage indicates the sense (or direction) in which the potential difference or voltage is acting. For example, if a second voltage is acting in the same direction as another voltage then it is acting in the positive sense; if it is acting in the opposite direction then in is acting in the negative sense'.It's very important to understand that you cannot apply 'positive' and 'negative' is the sense of charge or polarity to potential difference or voltage. You can, however, apply these terms to 'potential'. Potential is relative, and always measured with respect to a given point (often, the earth). So a point can be, for example, +5 V or -5 V with respect to another point (usually earth or ground, but not necessarily).Never confuse 'potential' with 'potential difference' and remember that 'voltage' means potential difference notpotential.So, to obtain a negative potential, earth (ground) the positive terminal of the battery or d.c. supply. All potentials measured relative to earth are now negative. To obtain a positive potential, earth the negative terminal of the battery or d.c. supply instead. All potentials measured relative to earth are now positive.If you want to get a negative potential,Earth the positive terminal of the DC power sourceConnect a resistor in series with the negative terminal of the sourceAt the other end of the resistor you get a negative potential (the value's less than the value of the power supply)
What is mean polar?
What is meant by polarity? Answer An electric charge has a polarity of either positive or negative. Also a voltage has a polarity, in that it could be positive or negative, with respect to some other voltage, such as the one at the other end of a battery or electric circuit.
In a 1.5V battery taking the negative terminal as 0.0V what is the electrical potential energy of an electron leaving the negative battery terminal?
Somebody is trying a trick question! The electron that comes out of the negative terminal has zero potential energy. With respect to the positive terminal it has -1.5V of electrical potential energy, and so does every other electron at 0.0V whether or not they came out of the battery.
What is the voltage reading of positive wire in 110V dc?
You should be asking, 'What is the potential reading of a positive wire....?', as 'voltage' means 'potential difference' and you can't have a potential difference on a wire! The positive wire has a potential difference of +110 V with respect to the negative wire.
What is the primary difference between the LM317 and LM337 regulators based on electrical engineering?
Both are 1.5A adjustable voltage regulators. The LM317 outputs a positive (with respect to ground) voltage, and the LM337 outputs a negative voltage.
What is negative 48 volt DC voltage?
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
What is the voltage reading of positive wire in 110V dc circuit?
You should be asking, 'What is the potential reading of a positive wire....?', as 'voltage' means 'potential difference' and you can't have a potential difference on a wire!

What is positive and negative dc voltage?
They are opposites of each other. This refers to the direction of the electrical current is flowing. A battery right side up has +4.6 volts across it. Current is flowing out of the top and I to the bottom. Flip it upside down, now measured the same way you'll see -4.6 volts, meaning current if flowing into the top and out of the bottom.Additional AnswerThere is no such thing as a 'positive' and 'negative' voltage if you are referring to 'positive' and 'negative' in the sense of polarity or charge. Voltage is simply another name for potential difference, and you cannot have a positively- or negatively-charged potential difference! Presumably, what your question should ask is "What is positive and negative potential?".The potential at any point in a circuit is measured with respect to another point in the same circuit -often, this is earth (or ground). For example, a car battery's negative terminal is usually earthed to the vehicle's metal chassis, so anything connected directly to its positive terminal has a potentialof +12 V.On the other hand, 'positive' and 'negative' can also refer to sense or direction, rather than polarity or charge. Used in this sense, you can apply these terms to potential difference or voltage. For example, if a second battery acts in the same direction as another battery, then its voltage is acting in the positive sense (or direction); if it is connected to oppose another battery, then its voltage is acting in the negative sense. Applying the terms 'positive' and 'negative', in this sense, to potential differences or voltages, is useful in various electrical theorems, such as Kirchhoff's.
How do you find the voltage at a point in a circuit with respect to a negative voltage?
First of all, 'voltage' means potential difference -and you cannot have a potential difference 'at a point'. Similarly, you cannot have a 'negative' potential difference, so it doesn't make sense to talk about a 'negative voltage'.Your question, therefore, should read: 'How do you find the potential at a point in a circuit with respect to a negative potential?'The answer is that you simply connect a voltmeter between the two points. The reading will give you the value of the potential. If it reads upscale, then it'll be positive; if it reads downscale, then it will be negative (i.e. even more negative tan the reference potential).
Can you call forward bias voltage as positive voltage?
it is not necessary that always positive voltage should act as a forward bias voltage , it is the potential difference between cathode and anode that makes it forward or reverse biased .it the anode(p- doped material) positive with respect to cathode(n- doped material) --> forward biasedit the anode(p- doped material) negative with respect to cathode(n- doped material) --> reverse biasedex.anode - 5v cathode - 3vanode - 1v cathode - -2vboth the examples are forward biased.
In hobowars how does your respect go up?
Your respect will increase if you beat hobos with negative respect and will decrease if you fight hobos with positive respect.
What is the voltage difference between positive and negative voltage?
The sign determines the direction of flow of electrons. This matters for direct current appliances and most things with computer chips in them, since memory storage, logic chips, diodes, LEDs, etc require current from one direction to operate. AC however, varies from positive to negative voltage sixty times per second (in the US- 60 Hz) which allows the power to transmit further distances through powerlines than DC would allow.Additional AnswerIt's important to understand that 'voltage' is another word for 'potential difference'. You cannot apply the terms 'positive' and 'negative', in the sense of 'polarity' or 'charge' to a potential difference or voltage. You cannothave a 'positive voltage' or a 'negative voltage' in this sense.'Positive' and 'negative', in the sense of polarity or charge can, however, be applied to potential. For example, you can say that an object has a "potential of +100 V or -100 V" with respect to another object. What you cannot say is that there is a potential difference of +100 V or -100 V between the two objects.The key to understanding this is that 'voltage' is another word for 'potential difference', NOT 'potential'. So you CANNOT have a 'positive or negative voltage' because we cannot have a 'positive or negative potential difference'.We can, though, apply the terms 'positive' or 'negative', in the sense of 'direction' to potential difference (or voltage). For example, we could arbitrarily apply a 'positive' direction to a voltage which acts clockwise around a closed loop, and a 'negative' direction to another voltage which acts counterclockwise around the same loop.So you need to sort out in your mind exactly what you mean by 'positive' and 'negative': charge (or polarity) or direction? And then re-phrase your question.
