# IT Rs V, ERL Nonideal source

Question

In the circuit shown in Figure P2.34, determine the
terminal voltage of the source, the power supplied to
the circuit (or load), and the efficiency of the circuit.
Assume that the only loss is due to the internal
resistance of the source. Efficiency is defined as the ratio of load power to source power.
VS = 12 V RS = 5 k RL = 7 k
