C) Three AC voltages are as follows:

ei = 80 sin wt volts;

e2 = 60 sin (wt + π/2) volts;

e3 = 100 sin (wt-π/3) volts.

Find the resultant e of these three voltages and express it in the form

Em sin wt+-&).

When this resultant voltage is applied to a circuit consisting of a 10 resistor and a

capacitance of 17.3 2 reactance connected in series, find an expression for the

instantaneous value of the current flowing, expressed in the same form.
