What is the equivalent ratio?
Given one ratio, p/q, you will obtain an equivalent ratio if you multiply p and q by any non-zero integer.
Is three forts a equivalent fraction?
Equivalent to what? When you talk about equivalent fractions, the idea is that two different fractions are equivalent, one to the other, or that they are not. For example, 3/4 is equivalent to 6/8 (or to any other fraction which you obtain by multiplying numerator and denominator by the same number).
What is the equivalent fraction of 910?
910, written in a=rational form, is 910/1. You can then multiply both, its numerator and denominator by the same positive integer to obtain an equivalent fraction. There are infinitely many of these so it is not possible to list them.
Which ratio is the same proportion as 21 to 36?
21/36 in lowest term is 7/12. Multiply both, the numerator and the denominator, by the same number in order to obtain equivalent fractions.
What is 2.100 rounded to the nearest thousandth?
2.100
I have three identical resistors all at 100 ohms in what combination can I put them to obtain a resistance of 66.7?
If you have three 100 ohm resistors, and you want an equivalent resistor of 66.7 ohms, put two resistors in series, and then parallel the third resistor across the first two. Resistors in series: R1 + R2 Resistors in parallel: R1 * R2 / (R1 + R2) This example: Two 100 ohm resistors in series: 100 + 100 = 200 A 100 ohm resistor in parallel with a 200 ohm resistor: 100 * 200 / (100 + 200) = 66.7
Using a 741 op amp how do you find the resistors values having a frequency of 1khz to obtain a sawtooth generator wave?
What kind of question is that. What resistors, what circuit are you talking about?
What is the use of resistance?
In electronic circuits, resistance is used to empede the flow of current. You may want a specific voltage at a given location, so by using resistors, you can obtain that voltage. You may want to limit current, which a resistor can do for you. But resistance is inherent in everything. Copper wire has resistance, your toaster is really nothing more than a resistor. Resistance is generally considered the load in electrical systems. If it were not for resistance, everything would be considered a short circuit. So you see resistance, although many times not desired, is required.
What is a resistors in circuit?
Resistors can be used to obtain desired voltages in other parts of the circuit. Or they can be used in conjunction with inductors and capacitors to affect a desired dissipation time (of voltage or current). A resistor may be made out of carbon or some other semiconducting material, or sometimes very long strands of conductor (silver for example) can be wrapped up to get very precise and consistent resistance values.
The resistance of earth wire is?
The recommended resistance that one should strive to obtain is zero.
When the output of two 5.6 volts zener diodes circuits are connected in series do you obtain 2x5.611.2 volts?
If you are saying that the Zeners are connected in series, the answer is Yes.
How do you compute the watt of heater with volt and resistance are the given?
You must first solve for current or amperage, if you know only voltage and resistance. The symbol for current is normally "I" or "A". The formula is A=V / R . So divide the voltage by the resistance to obtain the current. Then the formula for wattage or power (P) is P= V x A . So then you would multiply the voltage by the current to obtain the power in watts.
Are there any videos where metre bridge, commutator and Peltier's effect are explained together?
(a) The connection between the resistors in a meter bridge is made of thick copper strips because the resistivity of a copper wire is very low. As, the connections are thick, so the area becomes large and the resistance of the wires becomes almost negligible. (b) It is preferred to obtain the balance point in the middle of the meter bridge wire because it improves the sensitivity of the meter bridge. (c) Constant is used for meter bridge wire because its temperature coefficient of resistance is almost negligible due to which the resistance of the wire does not get affected on increasing temperature of the wire during flow of current.
What result should you obtain when you do megger tests for motor?
we will get its insulation resistance value wchich should be greater than 200Mohms
Why resistance use in silicon diode characteristics?
Resistance is used in characterizing silicon diodes, or any component for that matter, because the equivalent resistance in a certain condition tells you what the circuit will do in that condition. It is true that a diode is not a resistor, but it has an equivalent resistance at each point on it operating curve. Let take three points, for example... With one ampere of current, the forward voltage might be 0.68 volts. That corresponds, using Ohm's law, to a resistance of 0.68 ohms. With ten amperes of current, the forward voltage might be 1.15 volts. That corresponds to a resistance of 0.115 ohms. With 25 amperes of current, the forward voltage might be 1.7 voltage. That corresponds to a resistance of 0.068 ohms. You can obtain the forward resistance curve from the manufacturer's data sheet. Even if there is only a voltage versus current curve, you can calculate resistance using Ohm's law. You need to know the resistance curve in order to design the circuit that uses the diode. In high performance situations, such as in large power supplies, the resistance of the diode may well be critical, and would therefore be a factor in selecting which diode amongst several choices to choose.
What wire will allow high current to pass through without getting hot?
A wire with low resistance. To obtain the lowest resistance, the wire must be -- thick -- a good conductor; silver, copper, etc. -- cold
How much current will flow through a 2.4 kilohm resistor when 7.2 kilovolts is applied?
Divide the voltage by the resistance in order to obtain your answer.
