Question
A capacitor of 22μF and a resistor of 200Ω are connected in series across a 12V, 50Hz source. Calculate the impedance of the circuit.
Correct Answer
Option D is the correct answer.
Detailed Explanation
X_C = 1/(2πfC) = 144.7Ω. Z = √(R² + X_C²) = √(200² + 144.7²) = 246.9Ω
Hint
Impedance in an RC circuit is the vector sum of resistance and reactance.
