Field Effect Transistors (FET) - Technical MCQs

Q1:

A __________ change in VDS will produce a __________ change in ID.

A small, large

B large, small

C large, large

D small, small

ANS:B - large, small

Because VGS is the parameter that controlls ID and the value for ID is saturated at different values of VGS thus a large value of VDS only affects the ID slightly.
