Question

Solve the following:

 

A two - branch parallel circuit, with impedances Z = 4 2 –30° n and Z, = 5 Z 60º N has an applied effective voltage of 20 V. Obtain the power triangles for the branches and combine them to obtain the total power triangle. A three - branch parallel circuit, with Z, = 25 z 15º N, Z2 = 15 z 60º N, and Z3 = 15 z 90° N, has an applied voltage V = 339.4 2 –30° V. Obtain the total apparent power and the overall power factor.
