Explanation:
When the frequency is increased, the following effects can be observed:
1. Eddy current losses:
Eddy current losses in a magnetic material are directly proportional to the square of the frequency. Hence, if the frequency is increased, the eddy current losses will also increase. Therefore, option A is incorrect.
2. Hysteresis losses:
Hysteresis losses in a magnetic material are directly proportional to the frequency. Hence, if the frequency is increased, the hysteresis losses will also increase. Therefore, option B is incorrect.
3. Voltage:
As per the question statement, the voltage is remaining constant. Hence, there will be no change in the voltage level.
4. Eddy current losses and frequency:
The eddy current losses in a magnetic material are directly proportional to the square of the frequency. Therefore, if the frequency is increased, the eddy current losses will also increase. However, as the voltage is remaining constant, the eddy current losses will remain unchanged. Hence, option C is correct.
5. Hysteresis losses and frequency:
Hysteresis losses in a magnetic material are directly proportional to the frequency. Therefore, if the frequency is increased, the hysteresis losses will also increase. However, as the voltage is remaining constant, the hysteresis losses will remain unchanged. Hence, option D is incorrect.
Conclusion:
Hence, from the above explanation, we can conclude that if the voltage remains constant, and the frequency is increased, the eddy current losses will remain unchanged.
