14.Semiconductor Electronics
medium
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
A
$0-5\,\,V$
B
$0-24\,\,V$
C
$0-12\,\,V$
D
$0-8\,\,V$
(JEE MAIN-2016)
Solution
The minimum voltage range of $DC$ source is given by
$\mathrm{V}^{2}=\mathrm{PR}$
$ \because \,\, \mathrm{P}=1\,watt$,
$\mathrm{R}=100 \Omega$
$=1 \times 100$
$\therefore \mathrm{V}=10 \mathrm{volt}$
