In a series RL circuit, the phase difference between the applied voltage and the current increases if?

Understand the Problem

The question is asking about the factors that influence the phase difference between voltage and current in a series RL circuit, specifically under what conditions this phase difference increases.

More Information

In a series RL circuit, the phase difference between the applied voltage and the current is largely determined by the inductive reactance. Increasing the inductive reactance (XL), often by increasing the frequency of the AC supply, increases the phase difference because inductive reactance causes a larger delay in the current.

Tips

A common mistake is to assume resistance (R) impacts the phase difference as much as inductive reactance (XL); however, the primary influence on phase difference in an RL circuit is the inductive reactance.
