In the following circuit, the current flowing through zener diode is (a) 35 mA (b) 25 mA (c) 15 mA (d) 5 mA

Answer: (b). Zener holds 8 V across R₂: IR2 = 8/1600 = 5 mA. Voltage across R₁ = 20 - 8 = 12 V: IR1 = 12/400 = 30 mA. Iz = IR1 - IR2 = 30 - 5 = 25 mA So the answer is (b) 25 mA.

In the following circuit, the current flowing through zener diode is

Show answer and solution

Answer: (b)

Zener holds $8$ V across $R_2$ : $I_{R2} = \frac{8}{1600} = 5$ mA.
Voltage across $R_1 = 20 - 8 = 12$ V: $I_{R1} = \frac{12}{400} = 30$ mA.
$I_z = I_{R1} - I_{R2} = 30 - 5 = 25$ mA
So the answer is (b) 25 mA.
