In the given figure, a diode `D` is connected to an external resistance `R=100 Omega` and an emf of `3.5 V`. If the barrier potential developed across the diode is `0.5 V`, the current in the circuit will be :

A

40 mA

B

20 mA

C

35 mA

D

30 mA

Text Solution

Verified by Experts

The correct Answer is:
D
Current `= (( 3.5 -0.5))/(100) A = ( 3)/(100) A = 30 mA`
