Question

The equation of the alternating current is i = 35.36sin628t What will be the effective value

Answer 1

The effective value of the current will be 25 Amperes.

Explanation :

equation of current is given by,

i = I₀ sinωt

where I₀ = peak value

ω = angular velocity

comparing this with the given value we get ,

I₀ = 35.36

we know that the effective value of an alternating current is measured by its RMS value which is given by,

Irms = I₀/√2

=> Irms = 35.36/√2 = 25 Amperes.

Hence the effective value of the current will be 25 Amperes.
