Question

The N is defined as?

(a) output power/ input power

(b) input power/ output power

(c) output power at inductor/ input power

(d) output power at capacitor/ input power

I have been asked this question in semester exam.

This interesting question is from Series Equalizer in chapter Filters and Attenuators of Network Theory

Answer 1

Right choice is (b) input power/ output power

The best I can explain: The N is defined as the ratio of input power to the output power. N = Pi/Pl where Pi is input power and Pl is output power.
