A coil has a resistance of 10 Ω and an inductance of 0.1 H. It is connected to an AC source with f = 50 Hz. Find the impedance.
Q1. A coil has a resistance of 10 Ω and an inductance of 0.1 H. It is connected to an AC source with f = 50 Hz. Find the impedance.
Answer: √(100 + 100π²) Ω
Explanation: Z = √(R² + Xl²) = √(10² + (2π*50*0.1)²) = √(100 + 100π²) Ω.
