Question

A diode is said to be reversed biased when the

(a) cathode is positive with respect to the anode

(b) anode is positive with respect to the cathode

(c) cathode is negative with respect to the anode

(d) both cathode & anode are negative

This question was posed to me by my school principal while I was bunking the class.

My enquiry is from Power Diodes-1 topic in chapter Diodes of Power Electronics

Answer 1

Correct option is (a) cathode is positive with respect to the anode

For explanation I would say: K is positive w.r.t the A when the device is reversed biased.
