Question

Ac current is given by i=200 sin 100 it will achieve a value of 100 a after sevond

Answer 1

Hey Dear,

◆ Answer -

t = 1/600 s

● Explaination -

Given that,

i = 200.sin(100πt)

When, i = 100 A,

100 = 200.sin(100πt)

sin(100πt) = 1/2

Taking sininverse -

100πt = arcsin(1/2)

100πt = π/6

t = (π/6) / (100π)

t = 1/600 s

Therefore, the current will achieve value of 100 A at 1/600 th of second.

Thanks..
