Question

What would be the frequency of an alternating current after 0.01s?

Answer 1

f=1/T

f=1/0.01

f=100Hz

Answer 2

Answer:

So this is the half time of the complete time period (i.e. the time in which an alternating wave completes one cycle) as for an alternating current after half cycle the direction changes and this another half time is also equal to 0.01s. Now as we know that frequency (f) is the inverse of the time period (T). ⇒f=1T Hz.
