The question states an a.c. Voltage , V comprises of a fundamental voltage of 100 V rms at a frequency of 120Hz, a 3rd harmonic which is 20% of the fundamental, a 5th harmonic which is 10% of the fundamental and a phase angle of 1.2 radians lagging.
A) write down an expression for the voltage waveforms
B) Sketch the waveforms of the harmonic components
