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

`35 mA`

B

`30 mA`

C

`40 mA`

D

`20 mA`

Text Solution

Verified by Experts

The correct Answer is:
B

`I=((3.5-0.5)V)/(100 Omega)=30 mA`
