Question

capacitor 22µF, resistor 200Ω, series across 12V 50Hz. Impedance?
Options
A 100.0Ω
B 152.6Ω
C 212.5Ω
D 246.9Ω
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

X_C = 1/(2πfC) = 1/(2π×50×22e-6) = 1/(0.006908) ≈ 144.7 Ω. Z = √(R² + X_C²) = √(200² + 144.7²) = √(40000 + 20946) = √60946 ≈ 246.9 Ω.

Hint

Z = √(R² + X_C²).
