Question 3: The voltage v across a load and the current I into the positive polarity terminal are<br />
as follows (where 1 and 3 are not equal):<br />
v(t) = Vd + 2V1 cos(1t) + 2V1 sin(1t) + 2V3 cos( 3t) i(t) = Id + 2I1cos(1t) + 2I1cos( 3t 3) Calculate the following:<br />
a) The average power P supplied to the load<br />
b) The rms value of v(t) and i(t)<br />
c) The power factor at which the load is operating<br />
