- a)0, 90⁰
- b)1, 90⁰
- c)1, 0⁰
- d)0, 0⁰
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
In case of purely inductive circuit, average power = ____ and θ ...
In case of purely inductive circuit, the phase angle between the voltage and current is zero that is θ = 90⁰. Hence the average power = 0.
Most Upvoted Answer
In case of purely inductive circuit, average power = ____ and θ ...
Explanation:
Inductive Circuit:
An inductive circuit consists of a pure inductor connected to an AC voltage source. In this circuit, the voltage and current are out of phase by 90 degrees due to the inductive reactance of the inductor.
Power Calculation:
In a purely inductive circuit, the average power is zero. This is because the power is calculated as the product of voltage, current, and the cosine of the phase angle (θ), and in an inductive circuit, the phase angle is 90 degrees. The cosine of 90 degrees is zero, resulting in zero average power.
Phase Angle:
The phase angle in a purely inductive circuit is 90 degrees. This means that the voltage and current are 90 degrees out of phase with each other. The current lags behind the voltage in an inductive circuit.
Therefore, in the case of a purely inductive circuit:
- Average power = 0
- Phase angle (θ) = 90 degrees
So, the correct answer is option 'A': 0, 90.
