If the line frequency is 50 Hz, the output frequency of bridge rectifier is ____.
- A
50Hz
- B
100Hz
- C
200Hz
- D
150Hz
Correct Option:B
This option is correct because in the output of bridge rectifiers one half cycle is repeated, the frequency will be twice as that of input frequency, so f=100Hz.
a) 50Hz
Explanation: This option suggests that the output frequency of the bridge rectifier is 50 Hz, which is the same as the line frequency. However, this is correct.
Correct Option:B
This option is correct because in the output of bridge rectifiers one half cycle is repeated, the frequency will be twice as that of input frequency, so f=100Hz.
c) 200Hz
Explanation: This option suggests that the output frequency of the bridge rectifier is 200 Hz. However, this is not correct. As mentioned earlier, the output frequency of a bridge rectifier remains the same as the line frequency, which is 50 Hz in this case.
d) 150Hz
Explanation: This option suggests that the output frequency of the bridge rectifier is 150 Hz. However, this is not correct. The output frequency of a bridge rectifier is not changed or multiplied from the line frequency; it is the same as the input frequency, which is 50 Hz in this case.
