AC Theory Practice Questions and Answers | Latest Version | 2024/2025 | Graded A+ What happens to the voltage and current in a purely resistive AC circuit? In a purely resistive AC circuit, the voltage and current are in phase, meaning they reach their maximum and minimum values at the same time. What is the role of inductance in an AC circuit? Inductance in an AC circuit opposes changes in current by creating a magnetic field that induces a voltage opposite to the applied volt...
