An alternating current represented by

Question

I=8,75 sin (200piet .57.3)A

Answer 1

The given expression for the alternating current can be broken down as follows:

I = 8.75 sin (200πet/57.3) A

Here, "I" represents the current in amperes (A).
"π" is the mathematical constant pi, approximately equal to 3.14159.
"et" is the variable representing time in seconds (s).

To calculate the current at a specific time, substitute the value of "et" into the equation and simplify:

For example, if we want to find the current at t = 2 seconds,
I = 8.75 sin (200π(2)/57.3) A
I = 8.75 sin (400π/57.3) A
I ≈ 8.75 sin (22.089) A
I ≈ 8.75 x 0.37664 A
I ≈ 3.2976 A

Therefore, at t = 2 seconds, the alternating current is approximately 3.2976 A.
