Given the instantaneous value of current from a.c. source is I = 8 sin...
Given information:

Instantaneous value of current from a.c. source is I = 8 sin 623t

To find:

The r.m.s value of current

Solution:

The formula for calculating the r.m.s value of current is given by:

Irms = Im/√2

where Im is the maximum value of the current.

We know that the maximum value of the current is 8A (from the given equation).

So, the r.m.s value of current is:

Irms = Im/√2 = 8/√2 = 5.656 A

Therefore, the correct answer is option 'A'.

Conclusion:

The r.m.s value of current from the given a.c. source is 5.656 A.
