365324 Assertion :
The current through the \(pn\) junction is not same in forward and reversed bias.
Reason :
We can measure the potential barrier of a \(pn\) junction by putting a sensitive voltmeter across its terminal.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
