A 60 cycle AC, circuit has a resistance of `200 Omega` and inductor of 100 mH. What is the power factor? What capacitance placed in the circuit will make the power factor unity?

Explanation

To solve the problem step by step, we will calculate the power factor of the given AC circuit and then determine the capacitance required to make the power factor unity.

### Step 1: Identify the given values
- Resistance (R) = 200 Ω
- Inductance (L) = 100 mH = 100 × 10^(-3) H
- Frequency (f) = 60 Hz

### Step 2: Calculate the angular frequency (ω)
