Frequency of Instantaneous Power

The frequency of instantaneous power is determined by the product of the voltage and current waveforms.

Formula: Frequency of instantaneous power = Frequency of voltage/current x no. of cycles in one waveform

In this case, the voltage and current waveforms have a frequency of 50Hz. Therefore,

Frequency of instantaneous power = 50Hz x 1 cycle = 50Hz

Since one cycle of voltage and current waveforms is considered, the frequency of instantaneous power is also 50Hz.

Therefore, option C is incorrect and the correct answer is option B.

Summary

- The frequency of instantaneous power is determined by the product of the voltage and current waveforms.
- In this case, the voltage and current waveforms have a frequency of 50Hz.
- Therefore, the frequency of instantaneous power is also 50Hz.
- The correct answer is option B.
