An amplifier has an input resistance of 20 Ω, an output resistance of 10 Ω, and a short-circuit current gain of 3000.The signal source has an internal voltage of 100 mV rms and an internal impedance of 200 Ω.

The load is a 5- Ω resistance. Find the current gain, voltage gain, and power gain of the amplifier. If the power supply has a voltage of 12V and supplies an average current of 2A, find the power dissipated in the amplifier and the efficiency.
