In the circuit shown below, is working as a 8   V   d c regulated voltage source. When 12   V is used as an input, the power dissipated (in m W ) in each diode is (Considering both zener diodes are identical)

Correct answer

40

Step-by-step solution

i = 12 - 8 200 + 200 A = 4 400 = 10 - 2   A Power loss in each diode = 4 10 - 2   W = 40   mW
