What is the power factor of an A circuit containing inductor or capacitor ?

Explanation

To determine the power factor of an AC circuit containing either an inductor or a capacitor, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Power Factor**:
The power factor (PF) is defined as the cosine of the phase angle (φ) between the voltage and the current in an AC circuit. It can be expressed mathematically as:
\[
\text{Power Factor (PF)} = \cos(\phi)
