Two terminals aand bare identified as output terminals of a linear circuit containing
sinusoidal sources at a common frequency. The open-circuit voltage measured across
a–b is seen to be 100 V rms. The voltage phasor across a–bgoes down to 63.25 V rms
when a 20 Ω resistor is connected at the output and it goes down to 44.71 V rms when
a 10 Ω resistor is connected at the output. (i) Find the resistive load that will draw max-
imum average power from this circuit if a reactance can be introduced in series with
the resistive load and can be varied to maximise the power. (ii) Find the resistive load
that will ...
