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

Answer

Connecting circuit according to question, it is clear

$+\,ve$ terminal $1$, $-\,ve$ terminal $2$, resistance high.
