Problem 82-1    Source:  Problem elaborated by the author of the site.

In the circuit of the Figure 82-01.1, assuming a direct sequence, we have:

V_CA = 220 ∠30°  , and   Z_A = Z_B = Z_C = 10∠45°. Calculate:

a) The line and phase voltages.

b) The phase and line currents.

c) The total apparent power in the load.

d) The total actual power at the load.

e) The total reactive power in the load.
