Q. A Zener diode is connected to a battery and a load as shown below :
The currents $I, I_z$ and $I_L$ are respectively
JEE Main
JEE Main 2014
Semiconductor Electronics: Materials Devices and Simple Circuits
A
$15\, mA, 5 \,mA, 10\, mA$
19%
B
$15\, mA, 7.5\, mA, 7.5 \,mA$
10%
C
$12.5\,mA, 5 \,mA, 7.5\, mA$
10%
D
$12.5 \,mA, 7.5\, mA, 5 \,mA$
61%
Solution:
$I_{L} = \frac{10V}{2k\Omega} = 5mA$
$I = \frac{\left(60-10\right)v}{4k\Omega} = \frac{50}{4k\Omega} = 12.5\,mA$
$I_{Z} = I-I_{L} = \left(12.5-5\right)\,mA = 7.5\,mA$
