An experiment is performed to determine the $I-V$ characteristics of a Zener diode, which has a protective resistance of $R = 100 \,\Omega ,$ and a maximum power of dissipation rating of $1\,W$ .The minimum voltage range of the $DC$ source in the circuit is

The circuit shown below is working as a $8\; \mathrm{V}\;dc$ regulated voltage source. When $12 \;\mathrm{V}$ is used as input, the power dissipated (in $\mathrm{mW}$ ) in each diode is

(considering both zener diodes are identical)

In a zener diode, break down occurs in reverse bias due to

Zener breakdown takes place if

If voltage across zener diode is $6\, V$ then find out value of maximum resistance in this condition. (in $k \Omega$)
