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

Explanation:

Given that,

The instantaneous current in the circuit is giveen by :

We need to find the rms value of the current.

The general equation of current is given by :

It means,

We know that,

So, the rms value of current is 2.12 A.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
