Question

In a p-n junction diode the forward bias resistance is low as compared to
the reverse bias resistance. Give reason.​

Answer 1

Answer:

depltion layer of forward bias is small so lower potential barrirer so low resistance

Answer 2

In a p-n junction diode, the forward bias resistance is low in comparsion to

the reverse bias resistance due to the majority carriers that are responsible for current in forward biasing

• In forward biasing diffusion current flows driven by a concentration gradient

• If there is a small increase in forward voltage across the p-n junction, then it leads to a large increase in forward current. Hence the resistance is low in case of forward biasing.
