Special Purpose Diodes question from JEE Main 2021 (26 Aug, Shift 2)

Q67JEE Main 2021 · 26 AUG · SHIFT 2Medium

Special Purpose Diodes

For the given circuit, the power across Zener diode is .............. mW.

Numerical answer type. Work it out, then open the answer.

Show answer and solution

Answer: 120

$I = \frac{24 - 10}{1\text{ k}\Omega} = 14$ mA
$I_L = \frac{10}{5\text{ k}\Omega} = 2$ mA, so $I_Z = 14 - 2 = 12$ mA
$P_Z = V_Z I_Z = 10 \times 12 = 120$ mW
