Question

A series R-L-C circuit has R=10 Ohm, L=0.5H and C=10 uF. Calculate the impedance and phase angle of this circuit if it is connected to a source 100V, 50Hz.
Options
A 161.5 Ohm, 86.5 degrees
B 126.5 Ohm, -87.5 degrees
C 475.4 Ohm, 86.5 degrees
D 161.5 Ohm, -86.5 degrees
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

XL=157.1, Xc=318.3. Z=sqrt(10^2+(157.1-318.3)^2)=161.5. theta=arctan(-161.2/10)=-86.5 degrees.

Hint

XL=157.1, Xc=318.3.
