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. ​
