MCQ
$NPN$ transistor are preferred to $PNP$ transistor because they have
  • A
    Low cost
  • B
    Low dissipation energy
  • C
    Capability of handing large power
  • Electrons having high mobility than holes

Answer

Correct option: D.
Electrons having high mobility than holes
d
(d) In npn transistors electrons are majority charge carriers and in pnp transistors holes are majority charge carriers. Electrons have high mobility than holes and hence high mobility of energy.

Hence, $n-p-n$ transistors are preferred than $p-n-p$ transistors.
