The potential barrier at `PN` junction is due to

The potential barrier at a p-n junction is due to charges on either side of the junction. These charges are

In a PN -junction

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