In the circuit shown below, is working as a

8Vdc

regulated voltage source. When

12V

is used as an input, the power dissipated (in

mW

) in each diode is (Considering both zener diodes are identical)

In the circuit shown below, is working as a 8Vdc regulated voltage source. When 12V is used as an input, the power

In the circuit shown below, is working as a 8Vdc regulated voltage source. When 12V is used as an input, the power

Correct answer

Step-by-step solution

i = \dfrac{\left(12 - 8\right)}{\left(200 + 200\right)}A = \dfrac{4}{400} = {10}^{- 2}A

Power loss in each diode

= \left(4\right)\left({10}^{- 2}\right)W = 40mW
