Question

Assertion : The current through the $p-n$ junction is not same in forward and reversed bias. \ Reason : We can measure the potential barrier of a $p-n$ junction by putting a sensitive voltmeter across its terminals.

Professor PC Thomas Classes · Answer

(c) : We cannot measure the potential barrier of a $p-n$ junction by connecting a sensitive voltmeter across its terminals because in the depletion region, there are no free electrons and holes and in the absence of forward biasing, $p-n$ junction offers infinite resistance.
