AI Generated Solution

To find the phase difference between voltage and current in an AC circuit with a power factor of 0.5, we can follow these steps: ### Step 1: Understand the Power Factor The power factor (PF) is defined as the cosine of the phase difference (φ) between the voltage and the current in an AC circuit. Mathematically, it is expressed as: \[ \text{Power Factor (PF)} = \cos(\phi) \] ### Step 2: Set Up the Equation Given that the power factor is 0.5, we can write: ...
