Q1:

Typical values of current gains for CE, CB and CC amplifiers are

A 120, 120 and 1 respectively

B 120, 1 and 120 respectively

C 1, 120 and 120 respectively

D 1, 1 and 120 respectively

ANS:B - 120, 1 and 120 respectively

The common collector circuit can be shown mathematically to have a voltage gain of almost unity.
