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

In this case, the current leads the voltage by 80°, so the loss angle is 80°.

Option A is incorrect because it is the angle between the current and the voltage in an inductor.

Option C is incorrect because it is the angle between the current and the voltage in a resistor.

Option D is incorrect because it is the angle between the current and the voltage in a capacitor with a loss angle of 80°.
