An unknown transistor needs to be identified as `npn` and `pnp` type. A multimeter, wilth `+ve` and `-ve` terminals is used to measure resistance between different terminals transistor. If terminal `2` is the base of the transistor then which of the following is correct for a `pnp` transistor?

`+ve` terminals `3, -ve` terminal `2`, resistance high

`+ve` terminal `2, -ve` terminal `3`, resistance low

`+ve` terminal `1, -ve` terminal `2`, resistance high

`+ve` terminal `2,-ve` terminal `1`, resistance high

Text Solution

Verified by Experts

The correct Answer is:

when `pn` junction is forward biased resistance is law.
When `pn` junction reverse biased resistance is high
