You are wiring a LED lamp through a transformer you have a polarized plug and you know positive and negative The transformer is marked live and neutral Does live correspond with positive or negative?
LED's are DC voltage. Transformers are AC voltage. There is no positive or negative on AC voltage. You would need a diode to change the AC to DC, then there would be positive and negative voltages.
Positive logic in a logic circuit is one in which?
In Positive logic, we all assume that the more positive (binary) voltage state is One, the less positive voltage state is Zero.Both voltage states could be positive, both could be negative, or they could be opposite polarities.
What do imaginary numbers represent?
The real numbers together with the imaginary numbers form a sort of vector. What these complex numbers (complex means the combination of real and imaginary numbers) represent depends on the specific situation. Just as there are situations where it doesn't make sense to use negative numbers, or fractional numbers, in many common situations it doesn't make sense to use complex numbers. In an electrical circuit (specifically, AC), the real numbers might represent resistance, while the imaginary number represent reactance - and voltages and currents are also represented by complex numbers, with the angle of the complex number representing how much one quantity is ahead or behind another quantity (the "phase angle"). In quantum mechanics, the complex numbers might not represent anything (perhaps they don't, I am not sure...), but they are useful for calculations.
What is the X-Y operation of the oscilloscope?
The CRT display becomes an electronic graph of two instantaneous voltages. The display may be a direct comparision of two voltages such as during phase measurement, or frequency measurement with Lissajous waveforms.
What is the difference between milli volt meter and volt meter?
A milli voltmeter is suitable for measuring voltage/potential difference in milli volts, thus they measure smaller voltages. A regular voltmeter is used to measure comparatively larger voltages.
What method of polar encoding is used for a binary value 10110 with seven transitions between negative and positive voltages?
Differential Manchester
Suppose a bipolar alternative mark inversion signal uses the following voltages positive negative positive zero zero negative zero positive which bit stream does the signal represent?
11100101
Suppose that the binary value 10110 is transmitted and the polar signal contains seven transitions between negative and positive voltages what method of polar encoding was used in this case?
Differential Manchester
Define a direct short?
When there is a connection across both the positive and negative voltages.
How does DSU convert binary data pulses it receives from DTE?
the DSU converts the binary data pulses it receives from the DTE to the line encoding format required by the network, withing the computer the one bits are positive voltages, and zero bits are not voltages or low level voltages.
Why are both negative and positive voltages generated as the magnet passes through the coil?
In this context, 'negative' and 'positive' are used to indicate the sense, or direction, of the induced voltages, as voltages do not have electric polarity (+ or -). The direction of the voltage induced into a conductor is determined by the direction of that conductor relative to the magnetic field. As the coil rotates, the directions of each side of the coil reverse relative to the field, and the induced voltages reverse too.
What is analog rail?
The positive and negative supply voltages. Analog amplifiers clip a few volts short of their voltages, so these two supplies are usually 12 volts or more.
What do you Mean dual tracking power supply?
It's a power supply with a positive and negative voltage, where one of the voltages tracks the other. For example: the negative voltage tracks the positive. If you regulate the positive to 15v, the negative is going to be -15v. This allows very precise symmetric power.

Does an oscilloscope display both positive and negative voltage?
Yes. By convention, the horizontal line is deflected upward for positive voltages and down for negative. With no input, adjust the line to co-incide with a central line on the graticule. A varying voltage that remains positive will be deflected above the line. A voltage that transits from positive to negative will draw above and below the line.
What are signals composed of pulses of precise positive voltages and zero voltages?
Digital
