The device which allows reverse power flow and withstands highest switch frequency is (A) GTO (B) MOSFET (C) IGBT (D) Inverter grade SCR
The device which allows reverse power flow and withstands highest switch frequency is MOSFET
Burden of a protective relay is the power absorbed by the circuit of relay.
What happens when you reverse the direction of the current in an electromagnet?
When you reverse current direction in an electromagnet, the magnetic poles will also change.
What is a reverse conducting thyristor?
What is the difference between forward and reverse bias?
Forward bias is a PN junction bias which allows current to flow through the junction. Forward bias decreases the resistance of the depletion layer. Reverse bias is a PN junction bias that allows only ... Positive polarity on the n-type material and negative polarity to the p-type material.
A diode in which the change in reverse bias voltage varies the capacitance is called as A) Varactor diode B) Switching diode C) Tunnel diode D) Zener-diode
A diode in which the change in reverse bias voltage varies the capacitance is called as Varactor diode
How can we reverse the direction of rotation of synchronous motor?
By reversing supply phase sequence we can reverse the direction of rotation of synchronous motor.
In cut-off region of BJT both the emitter-base junction and collector-base junction are reverse biased.
What is phase failure relay and how it's work?
What is the difference between relay and contactor?
Relay have smaller ratings. Contactor is a high rating relay.
