To make a `PN` junction conducting

In a PN -junction

In a PN -junction diode

In a PN -junction diode

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.

The potential barrier at PN junction is due to

The depletion layer in PN junction diode is caused by.

The current through an ideal PN -junction shown in the following circuit diagram will be
