The resistance of p-n junction is low when forward biased and is high when reverse biased. Explain.
Text Solution
Verified by Experts
A small increase in forward voltage across p-n junction shows large increase in forward current. Hence the resistance `(="voitage /current")` of p-n junction is low when forward biased. A large increase in reverse voltage across p-n junction shows small increase in reverse current. Hence the resistsnce of p-n junction is high when reverse biased.
