### Problem 7:

**Context:**
A resistor that draws 12A, a 79.618mH inductor that draws 16A, a resistor of unknown value, and an inductor of unknown value are parallel-connected to a 60Hz source. The total circuit current is 56.347A, and the circuit power factor is 78.088%. The inductors have negligible resistance.

**Objective:**
Analyze the circuit by finding the following parameters:

**Parameters to Determine:**
- A. Circuit voltage
- B. Circuit impedance
- C. Circuit apparent power
- D. Circuit phase angle (indicate lead or lag)
- E. Value of the unknown inductor
- F. Value of the unknown resistor
- G. Total true power
- H. Total reactive power
- I. Current drawn by the unknown inductor
- J. Current drawn by the unknown resistor

Each of these parameters can be calculated using fundamental electrical engineering principles such as Ohm's Law, Kirchhoff's laws, and the formulae for power, impedance, and reactance in AC circuits.
