In a p-n junction diode, the increase in forward voltage of 0.19V increases the forward current by 37.6 mA, The dynamic resistance of the junction is

A

2 ohm

B

3 ohm

C

4 ohm

D

5 ohm

Text Solution

Verified by Experts

The correct Answer is:
D
`r_(a.c)=(DeltaV)/(DeltaI)=(0.19V)/(37.6mA)=(0.19V)/(37.6xx10^(-3)A)=5 ` ohm
