Question

A zener diode of 10v is connected in series with unknown resistance​

Answer 1

Answer:

my answer is 600 ohm

Explanation:

resis vol. is 30v

and current is 50m

so resis. is 600ohm

Answer 2

The minimum value of resistance will be 1K ohm.

Explanation:

Iz = 50 mA

Vz = 10 V

Vs = 40 V  

First draw the circuit according to the given data in the question. Then apply KVL on that circuit.

By Applying KVL, we get,

-40 - 10 + (50m) R = 0  

By solving for R, we get,

R = 1K ohm
