An amplifier with an input impedance of 50 K-ohm, an open circuit voltage gain of 150 V/V, and an output impedance of 100 ? is connected between a 5 K-ohm signal source and a 1 K-ohm load.
a) Find the overall voltage gain Gv.
b) Find the current gain defined as the ratio of the load current to the current drawn from the signal source.
