An alternating voltage with a frequency of 50 Hz has a period of
A
0.02 s
B
0.20 s
C
0.05 s
D
0.50 s
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
The period of a wave is the reciprocal of its frequency.
Therefore, period = \(\frac{1}{\text{frequency}}\)
Substituting the given frequency,
we get period = \(\frac{1}{ 50}\) Hz = 0.02 s.
