Question

An a.c. voltage, V, comprises of a fundamental voltage of 100 V rms at afrequency of 120 Hz, a 3rd harmonic which is 20% of the fundamental, a5th harmonic which is 10% of the fundamental and at a phase angle of1.2 radians lagging.(i) Write down an expression for the voltage waveform.(ii) Sketch the waveforms of the harmonic components.(iii) Determine the voltage at 20 ms.(iv) Given an ideal V = 100 V rms, what is the percentage error at 20 ms?

Robert · Accepted Answer

The ac voltage contains the following components: 
(a) Fundamental voltage of 100V rms at 120 Hz frequency ( 120**2,21001  mV ). The 
corresponding equation of wave is )240sin(21001 tV 
(b) 3rd harmonic voltage is 20V rms (20% of fundamental) at 3x120=360 Hz frequency  (
360**2,
