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?

Which of the following types of semiconductor are used in transistors?

In a PNP transistor, N-type semiconductor is used as the

One way in which the operation of an npn transistor differ from that of a pnp transistor is that

A working transistor with its three legs marked P, Q and R is tested using a multimeter No conduction is found between P, Q by connecting the common (negative) terminal of the multimeter to R and the other (positive) terminal to P or Q some resistance is seen on the multimeter . Which of the following is true for the transistor ?
