Question
A nonideal voltage source is modeled in Figure
P3.72 as an ideal source in series with a resistance that
models the internal losses, that is, dissipates the same
power as the internal losses. In the circuit shown in
Figure P3.72, with the load resistor removed so that
the current is zero (i.e., no load), the terminal voltage
of the source is measured and is 20 V. Then, with
RL = 2.7 kΩ, the terminal voltage is again measured
and is now 18 V. Determine the internal resistance and
the voltage of the ideal source.
