When the `P` end of `P-N` junction is connected to the negative terminal of the battery and the `N` end to the positive terminal then diode behaves as

Options

A. a super conductor
B. an insulator
C. a semiconductor
D. a conductor

Answer

B

Explanation

When the p-end of the p-n junction is connected to the negative terminal and n-end to the +ve terminal of a battery, the p-n junction becomes reverse biased. Its resistance becomes very large. Thus it behaves like a capacitor whose two conducting plates are separated by an insulator.
