When frequency is 50Hz, Time period is
0.01
0.1
0.02
0.05
0.01
Quick Summary: Given: Frequency (f) = 50 Hz
Frequency (f) = 50 Hz
T=f1
Identify the relationship
The time period (T) of an alternating current wave is defined as the reciprocal of its frequency (f).
T=f1
Substitute the given value
Given that frequency f=50 Hz, substitute this value into the formula.
T=501
Calculate the result
Performing the division results in the time period in seconds.
T=0.02 seconds
C is correct because the reciprocal of 50 Hz frequency is 0.02 seconds.
This relationship is fundamental in power systems; remember that standard grid frequency in India is 50 Hz, meaning every cycle repeats exactly every 20 milliseconds.
