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 :

Options

A. 35 mA
B. 30 mA
C. 40 mA
D. 20 mA

Answer

B

Explanation

`i=(V_("net"))/(R_("net"))=(3.5-0.5)/(100)`
`=(3)/(100)`Amp.
=30mA.
