*An amplifier with +40dB voltage gain, an input resistance of 10k and an output resistance of 1k is used to drive a 1k load.*

What is the value of Avo? Also find the power gain in dB.

What is the value of Avo? Also find the power gain in dB.

(solutions: 100V/V ; 44dB)

I found

**Avo = 200 V/V**(that's wrong for the solution) and I don't know how to determine the

**power gain**value... I know I should calculate the product of Av and Ai (voltage gain times current gain) but I have no data to find either the output or input current of the circuit.
