The instantaneous values of two alternating currents are given by i, = 20 sin wt and i, = 10 sin (wt + :) A. Find the sinusoidal expression for (i1 + i2) by drawing phasors and by calculations. Two alternating voltages are given by vị = 120 sin wt volts and vz = 200 sin(wt -) volts. Obtain the sinusoidal expression for v1 – v2 by resolution of phasors.
