Question

if the instantaneous current in the circuit is giveen by I=3 sin theta amperes, the rms value of the current will be

Answer 1

`I_(rms)=2.12\ A`

Step-by-step explanation:

Given that,

The instantaneous current in the circuit is giveen by :

`I=3\sin\theta\ A`

We need to find the rms value of the current.

The general equation of current is given by :

`I=I_o\sin\theta`

It means,
`I_o=3\ A`

We know that,

`I_(rms)=(I_o)/(\sqrt2)\\\\=(3)/(\sqrt2)\\\\=2.12\ A`

So, the rms value of current is 2.12 A.
