Q1:

The load impedance ZL of a CE amplifier has R and L in series. The phase difference between output and input will be

A 180°

B 0

C more than 90° but less than 180°

D more than 180° but less than 270°

ANS:D - more than 180° but less than 270°

It is 180° for purely resistive load and between 180° and 270° for R-L load.
