voltage

Pronunciation American British Australian Indian
n.
  1. the rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in volts; electromotive force; emf
  2. the difference in electrical charge between two points in a circuit expressed in volts; electric potential; potential; potential difference; potential drop

Cockcroft and Walton voltage multiplier

Pronunciation American British Australian Indian
n.
  1. a high-voltage machine in which rectifiers charge capacitors that discharge and drive charged particles through an accelerating tube; Cockcroft and Walton accelerator; Cockcroft-Walton accelerator; Cockcroft-Walton voltage multiplier

Cockcroft-Walton voltage multiplier

Pronunciation American British Australian Indian
n.
  1. a high-voltage machine in which rectifiers charge capacitors that discharge and drive charged particles through an accelerating tube; Cockcroft and Walton accelerator; Cockcroft-Walton accelerator; Cockcroft and Walton voltage multiplier

voltage divider

Pronunciation American British Australian Indian
n.
  1. resistors connected in series across a voltage source; used to obtain a desired fraction of the voltage; potential divider

voltage drop

Pronunciation American British Australian Indian
n.
  1. a decrease in voltage along a conductor through which current is flowing
E.g.
  • The voltage drop due to the lead resistance has been cancelled out.
  • At higher currents the forward voltage drop of the diode increases.
  • Four-terminal sensing eliminates voltage drop in the measuring leads as a contribution to error.

voltage regulator

Pronunciation American British Australian Indian
n.
  1. a transformer whose voltage ratio of transformation can be adjusted

high voltage

Pronunciation American British Australian Indian
E.g.
  • The oscillator must supply the high voltage and the yoke power.
  • Iron-core coils look like oil-filled high voltage transformers.
  • The system does not degrade gracefully under high voltage faults.

output voltage

Pronunciation American British Australian Indian
E.g.
  • Depending on the output voltage, the gain of the circuit varied from 1:1 to 1:10.
  • A bootstrap capacitor is connected from the supply rail (V+) to the output voltage.
  • Op amps scale the output voltage so that it is usable with the rest of the computer.

low voltage

Pronunciation American British Australian Indian
E.g.
  • Wood poles can also be used for low voltage distribution to customers.
  • The location makes low voltage (around 12 volt) distribution practical.
  • Modern systems are operated with relatively low voltage, usually from 6-12 volts.

voltage across

Pronunciation American British Australian Indian
E.g.
  • The voltage across the loudspeaker terminals is measured and considered proportional to the impedance.
  • One such property is the piezoelectric effect, where a voltage across the crystal can shrink or stretch it.
  • Changing the DC voltage across the varactor changes its capacitance, which changes the resonant frequency of the tuned circuit.

input voltage

Pronunciation American British Australian Indian
E.g.
  • Typically, as the input voltage increases, progressively more diodes conduct.
  • This causes negative feedback, and the output voltage tends to follow the input voltage.
  • A non-zero value for "h" means the output voltage affects the input voltage, that is, this amplifier is bilateral.

supply voltage

Pronunciation American British Australian Indian
E.g.
  • This is many times greater than household power supply voltage.
  • The main difference between the 6581 and the 8580 is the supply voltage.
  • The d.c. supply voltage equates to the average, so the tap peaks at approximately (pi/2)*Vcc.

voltage and current

Pronunciation American British Australian Indian
E.g.
  • Because lightning bolts vary in voltage and current, a more average calculation would be 10 gigawatts.
  • Vizag 2 was built by ABB between 2002 and 2005 and has nominal DC voltage and current ratings of 176 kV, 2841 A.
  • Vizag 1 was built by Alstom between 1996 and 1999 and has nominal DC voltage and current ratings of 205 kV, 2475 A.

voltage source

Pronunciation American British Australian Indian
E.g.
  • Typically a lower voltage source, such as a 9–volt battery, is sufficient for the purpose.
  • One end of the faulted cable is connected through a pair of resistors to the voltage source.
  • Circuits take in a voltage source, and modify them using resistors, capacitors, inductors, and other components.

voltage is applied

Pronunciation American British Australian Indian
E.g.
  • To achieve the ON condition of the display, a voltage is applied to the transparent electrode.
  • A high voltage is applied across the anode and cathode, resulting in an ionization of the fill gas.
  • When a voltage is applied to the device, the electrical gradient will be largest across the thin middle layer.
