1. The problem statement, all variables and given/known data

Two circuits of impedance (9-j4) and (12+j15) are connected in parallel across a 90 volt ac generator. Determine, the phase angle between this current and the supply voltage.

Voltage = 90V ac
Xc/Z1 = (9 - j4)
XL/Z2 = (12 + j15)
Current = 11.27 Amps
Total impedance = 7.98
