Answer to Question #20810 in Electricity and Magnetism for sanki

Question

A periodic voltage consists of sinusoidal pulses having an amplitude of 150 V. Use Fourier to calculate:
the amplitude of the DC component,
the fundamental,
the effective value of the voltage,
the effective value of all the harmonics.
V(θ) = 150 sin(θ), 0
0 ≤ θ ≤ 180°
180 ≤ θ ≤ 360°
