Question
An inductor L = 1 H in series with a resistor R = 150 ohms is connected to an A.C. source of 60 V, 50 Hz. Determine the impedance of the circuit.
Correct Answer
Option D is the correct answer.
Detailed Explanation
XL=2*pi(50)(1)=314.2. Z=sqrt(150^2+314.2^2)=348 ohms.
Hint
XL=2*pi(50)(1)=314.2.
