Transistors and Applications

Q1:

The gate-source junction of a JFET must be ________ for proper linear operation.

A forward-biased

B reverse-biased

C either forward-biased or reverse-biased

D neutral

ANS:B - reverse-biased

Because, for proper opration of BJT EB junction is always forward bias and CB junction is reverse bias.But for the JFET operation EB junction is reverse biase and CB junction is forward biase. Here gate-source junction is reverse-biased.
