Example Sheet 2 - AC Theory
1. Sketch two cycles of a 50 Hz sinusoidal voltage waveform. with an RMS of 240 V. Mark on the sketch the relative positions of the half cycle average, rms and peak values of the waveform, and indicate the period of the waveform, with their values.
2. Calculate the average and RMS values for the following waveforms:
(a) Sawtooth waveform.
(b) Square waveform.
(c) Discontinuous triangular waveform.
(Hint: Move the start of the time period to beginning of the waveform.
