Find the time...

Question

Find the time by alternating current to attain zero from peak value. the frequency of alternating current is $50$ Hz.

Open in App

Solution

IN $A C$
F = $\frac{1}{T}$
$T = \frac{1}{f} = \frac{1}{50}$
T = $0.02$ sec
Time taken by alternating current to attain zero from from peak is $\frac{T}{4} = \frac{0.02}{4} = 0.005 s e c$
