Four e.m.f.s, e1 = 100 sinωt, e2 = 80 sin(ωt − π/6), e3 = 120 sin(ωt + π/4) and e4 = 100 sin(ωt − 2π/3), are induced in four coils connected in series so that the sum of the four e.m.f.s is obtained. Find graphically or by calculation the resultant e.m.f. and its phase difference with (a) e1 and (b) e2.
If the connections to the coil in which the e.m.f. e2 is induced are reversed, find the new resultant e.m.f.
