List of top Physics Questions on Transistors asked in NEET (UG)

The electron concentration in an $n$-type semiconductor is the same as hole concentration in a $p$-type semiconductor. An external field (electric) is applied across each of them. Compare the currents in them.

The input resistan ce o f a silicon transistor is $100 \,\Omega$ B a se current is changed by $40 \,\mu A$ which results in a change in collector currently by $2 \,m A$ . This transistor is used as a comm on emitter amplifier with a load resistance o f $4 \,k\Omega$ The voltage gain o f the amplifier is

The core of a transformer is laminated because :-

The correct relation for $\alpha, \beta$ for a transistor

The part of the transistor which is heavily doped to produce large number of majority carriers is
