The average value of the non-sinusoidal current wave i(t) = 3 + 2 sin(ωt - 53°) + 0.8 sin(2ωt - 70°) A over one complete period is:

In an inductive circuit, a resistance of 2 Ω is connected in series with an inductor having an inductive reactance of 4 Ω. Determine the power factor of the circuit when connected to a single-phase AC supply.

A capacitor draws a reactive power of 100 VAR due to a current of 0.87 A. Determine the capacitive reactance (XC) of the capacitor.
