Verified Answer
In case of purely capacitive circuit, average power = ____ and θ...
In case of purely capacitive circuit, the phase angle between the voltage and current is zero that is θ = 90⁰. Hence the average power = 0.

In case of purely capacitive circuit, average power = ____ and θ...
Explanation:
Power in a purely capacitive circuit:
- In a purely capacitive circuit, the current leads the voltage by 90 degrees.
- The power in a circuit is given by the formula: P = VIcos(θ), where θ is the phase angle between voltage and current.
- In a purely capacitive circuit, the power factor (cos(θ)) is 0 since the phase difference is 90 degrees.
- Therefore, the average power in a purely capacitive circuit is 0.
Phase angle (θ) in a purely capacitive circuit:
- In a purely capacitive circuit, the voltage leads the current by 90 degrees.
- The phase angle θ is the angle by which the current leads the voltage or vice versa.
- In a purely capacitive circuit, the phase angle θ is 90 degrees.
Therefore, in the case of a purely capacitive circuit, the average power is 0 and the phase angle θ is 90 degrees. This is because the power factor is 0 due to the 90-degree phase difference between voltage and current in a purely capacitive circuit.
