The current flowing through an ac circuit is given by I = 5 sin 120 π t   A . How long will the current take to reach the peak value starting from zero?

Question

The current flowing through an ac circuit is given by I = 5 sin 120 &#960; t &#160; A . How long will the current take to reach the peak value starting from zero?

Aicharya · Accepted Answer

If initial value of current is zero, then it will take $\frac{T}{4}$ time to reach the peak value, where $T =$ time period.

As we know, $ω = 120 π$

Therefore,

$t = \frac{T}{4} = \frac{\frac{2 π}{ω}}{4}$ $= \frac{π}{2 ω} = \frac{π}{2 \times 120 π} = \frac{1}{240} s$
