In `PN`-junction diode the reverse saturation curren is `10^(-5)` amp at `27^(@)C`. The forward current for a voltage of `0.2` volt is

A

`2037.6xx10^(-3) amp`

B

`203.76xx10^(-3) amp`

C

`20.37xx10^(-3) amp`

D

`2.0376xx10^(-3) amp`

Text Solution

Verified by Experts

The correct Answer is:
C
The forward current
`i=i_(s)(e^(eV//kT)-1)=10^(-5)[e^((1.6xx10^(-19)xx0.2)/(1.4xx10^(-23)xx300))-1]`
`=10^(-5)[2038.66-1]-20.376xx10^(-3)A`
