What’s the efficiency of a source-load system that is impedance matched? This just means that the output impedance of the source is matched to the input impedance of the load.
(a) 100%
(b) 80%
(c) 70.79%
(d) ........
(b) 80%
(c) 70.79%
(d) ........
The answer is 50%. Impedance matching ensures that 50% of the power is dissipated in the source impedance and the other 50% in the load.
