Question

If peak voltage for a half wave rectifier circuit is 5V and diode cut in voltage is 0.7, then peak inverse voltage on diode will be?

(a) 5V

(b) 4.9V

(c) 4.3V

(d) 6.7V

I had been asked this question in an interview for internship.

I need to ask this question from Half-Wave Rectifier in chapter Application of Diodes of Electronic Devices & Circuits

Answer 1

The correct option is (c) 4.3V

For explanation: PIV is the maximum reverse bias voltage that can be appeared across a diode in the given circuit, If the PIV rating is less than this value of breakdown of diode will occur. For a rectifier, PIV=Vm-Vd=5-0.7=4.3V.
