If the current in a capacitor leads the voltage by 80°, the loss angle of the capacitor is_________________?

Correct answer: A. 10°

A. 10°
B. 80°
C. 120°
D. 170°

Explanation

For a practical capacitor, the current leads the voltage by slightly less than 90°. The loss angle is the deficiency from 90°, so it is 90° − 80° = 10°.
