MHT CET Physics question

The value of the zener current

(A)is determined by the zener voltage
(B)is always in the a microampere range
(C)does not depends upon the temperature
(D)is limited by the external circuit resistanceCorrect

Answer: (D)

Solution

In breakdown the zener voltage stays nearly constant while the current can rise to large values, so the current is set (and limited) by the external series
