Transistors and Applications - Technical MCQs

Q1:

A JFET

A is a current-controlled device

B has a low input resistance

C is a voltage-controlled device

D is always forward-biased

ANS:C - is a voltage-controlled device

When the voltage is increased at the input then current increased at output that is why it is voltage controlled current source.

And we are changing voltage that is we are changing electric field. By that we named it as field effect Transistor.
