A non-sinusoidal voltage has a Fourier Series :
V(t) = 10 + 30 Cos(2π60t+300) + 20 Cos(4π60t-600) + 25Cos(2π60t-200)+10 Cos(4π60t-300)
This voltage is connected to a load which is 10? resistor and 20mH inductor connected in series.
Find:
i) The RMS voltage
ii) The average voltage across the inductor
iii) Find the current i(t)
iv) Find the real power in second harmonic
v) The total real power absorbed by the load
