Assume that 30 V and 5 A are chosen as base voltage and current for the circuit of Problem 2.1.

a) Find the corresponding base impedance and VA.

b) Find the phasor currents I2 and I3 in per unit.

c) Determine the source apparent power in per unit.

Problem 2.1

In the circuit shown in Figure 2.35, the source phasor voltage is V = 30∠15°. Determine the phasor currents I2 and I3 and the impedance Z2. Assume that I1 is equal to five A. Calculate the apparent power produced by the source and the individual apparent powers consumed by the 1 -ohm resistor, the impedance Z2, and the resistance R3. Show that conservation of power holds true.
