A 500-turn coil is connected to a 60 Hz AC source. If the coil has an inductance of 0.5 H, what is the frequency at which the coil's inductive reactance is 50 Ω?
Q1. A 500-turn coil is connected to a 60 Hz AC source. If the coil has an inductance of 0.5 H, what is the frequency at which the coil's inductive reactance is 50 Ω?
Answer: 20 Hz
Explanation: Using the inductive reactance formula, the new frequency is calculated from X = 2 * π * f * L, giving 20 Hz
