A transistor has a power dissipation rating of 25 W. Assume that the transistor is the only element that dissipates power in the circuit. Calculate the power an amplifier using this transistor could deliver to the load if it operates:

(a) Class A with an efficiency of 30%

(b) Class C with an efficiency of 80%
