(unit of measurement of electromotive force, or pressure, in an electrical circuit, or 'push', named for Alessandro Volta (1745-1827) renowned for his pioneering work in electricity)
2. The ratio of the phasor representing the magnitude and phase of the electric field of the backward-traveling wave at a specified cross section of a waveguide to the phasor representing the forward-traveling wave at the same cross section.
2. The change in voltage magnitude that occurs when the load (at a specified power factor) is reduced from the rated or nominal value to zero, with no intentional manual readjustment of any voltage control, expressed in percent of nominal full-load voltage.
Voltage regulation is a convenient measure of the sensitivity of a device to changes in loading.
2. A device that maintains the terminal voltage of a generator or other voltage source within required limits despite variations in input voltage or load.
3. A circuit that includes a sensor capable of monitoring the load and restoring the output voltage to close tolerance limits despite changes in both the load and the input voltage.
4. Any electrical or electronic device that maintains the voltage of a power source within acceptable limits.
The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage.
Voltage regulators also are used in electronic equipment in which excessive variations in voltage would be detrimental.
The term anode is a general term for the electrode, terminal, or element through which current enters a conductor; so called from the path the electrical current was thought to take.2. A situation in which the anode current of an electron tube can not be further increased by increasing the anode voltage.
The electrons are then being drawn to the anode at the same rate as they are emitted from the cathode.
2. A transformer utilized o transform voltage with little or no current.
3. A small step-up transformer used for increasing the sensitivity for an AC voltmeter.
4. An instrument transformer that has a primary winding connected in parallel with a circuit in which the voltage is to be measured or controlled.
2. An oscillator having an output frequency that varies with the applied direct current control voltage.
3. An electronic oscillator designed to be controlled in oscillation frequency by a voltage input.
3. An oscillator having an output frequency that varies with the applied direct current control voltage.
2. A pair of circuits in which the elements of one circuit are replaced by their dual elements in the other circuit according to the duality principle; for example, currents are replaced by voltages, capacitances by resistances.
