The constants of an amplifier are given by A = 1, Ri =10,000, and Ro = 100. It is driven by a Thévenin source with vTh(t) = VOcos ωt and RTh = 20,000 . The amplifier output is connected to a 100 - load resistance. Find the power amplification, if it is defined as the ratio of the power delivered to the load to the maximum power available from the Thevenin source.
