Q1.

A certain power transistor meant for Class A amplifiers has a zero-signal power dissipation of 20 W. Find the power rating of the transistor if the ac output power is 5W.

40 W

100 W

4 W

20 W

: min

Explanation

Solution:

The power dissipation capacity if the transistor should be at least equal to zero – signal power dissipation, i.e., 20 W. This is because the zero – signal condition represents the worst condition for the transistor.
