What is restriking voltage?
Restriking voltage is the voltage that appears across the contacts of a circuit breaker after the current-carrying contacts separate during an interruption. It occurs due to the re-ignition of the arc between the contacts, creating a momentary rise in voltage in the circuit. This can potentially damage the circuit breaker and equipment if not properly managed.
What is restriking voltage and recovery voltage?
Restriking Voltage : it is the transient voltage that exists during the arcing time. ( natural frequency kHz ). Recovery Voltage : it is the rms voltage after final arc extinction. ( normal frequency 50 or 60 Hz). both voltages appear between circuit breaker poles.
Other name of voltage to current converter?
a FET, or Feild Effect Transistor. In a FET, the value of the current depends upon the value of the voltage applied at the gate and drain so it is known as a voltage controlled device. For example: In a MOSFET the current from drain to source depends upon the width of the depletion layer which in turn depends upon the voltage applied on the gate.
How does the maximum value of the current depend on the frequency of the AC voltage source?
The maximum value of the current in an AC circuit depends on the frequency of the voltage source. As the frequency increases, the maximum current value also increases.
Why is it thatFET is called a voltage operated device?
since in an FET the value of the current depends upon the value of the voltage applied at the gate and drain...so it is known as voltage controlled device.. for example..in a mosfet..the current from drain to source depends upon the width of the depletion layer..which in turn depends upon the voltage applied on the gate.. so that is the reason
Is it true that the higher a resistance value the higher the voltage drop?
Greater value resistor will absorb more voltage than smaller value. The more voltage absorb with same value current flow, the larger body mass resistor will require. Body size depends on type of resistor (material resistor is made of).
How many amps to a kilowatt?
The relationship between amps and kilowatts depends on the voltage of the circuit. To calculate the amperage for a given kilowatt value, you need to know the voltage as well. The formula to convert kilowatts to amps is Amps = (kW * 1000) / Volts.
What is the value of the breakdown voltage for zener diode?
It depends on the particular diode. They come in all different values.
What is the acceptable pi value in insulation resistance?
The PI value depends on the type of equipment being tested and the voltage level. Roughly it shall not be below the value of 2.0
What is transient voltage?
A transient voltage is a time varying voltage value. Transient says that the voltage value changes, especially from a steady state, to a new value, then back again.
What is voltage amplitude?
Voltage amplitude is the maximum value of a voltage.
What is breakdown voltage of diode?
The critical value of the voltage, at which the breakdown of a P-N junction diode occurs is called the breakdown voltage.The breakdown voltage depends on the width of the depletion region, which, in turn, depends on the doping level. The junction offers almost zero resistance at the breakdown point.
