If the forward bias voltage of a p-n junction diode is changed form 0.7 V to 2.2 V, the forward current changes by 1.5 mA , then the depletion layer is

Options

A. `100 Omega`
B. `500 Omega`
C. `1000 Omega`
D. `5000 Omega`

Answer

C

Explanation

`r_(f)=(deltaV)/(deltaI)=(2.2-0.7)/(1.5xx10^(-3))=1000 Omega`
