A certain RL series combination is connected across a 50 hertz single ...

Calculation of Power Factor Angle:

- The instantaneous power drawn being negative for 2 milliseconds in one cycle indicates that the circuit is absorbing power for less than half of the cycle.
- This implies that the power factor angle is less than 45 degrees since a power factor of 1 (cosine of 0 degrees) would mean power is being absorbed for the entire cycle.

Determination of Power Factor Angle:

- Since the power factor angle is less than 45 degrees, we can eliminate option D.
- To further narrow down the options, we need to consider the remaining possibilities based on the given information.
- A power factor angle of 9 degrees would correspond to a situation where power is being absorbed for a very small portion of the cycle, which is unlikely given the negative power observed for 2 milliseconds.
- A power factor angle of 18 degrees would indicate that power is being absorbed for slightly more than half of the cycle, which is also inconsistent with the given scenario.
- A power factor angle of 36 degrees aligns with the negative power observed for 2 milliseconds in one cycle, where power is being absorbed for less than half of the cycle but not for a negligible amount.

Therefore, the power factor angle of the circuit must be 36 degrees (Option C).
