Bot GPT 3.5 The given expression for the alternating current can be broken down as follows:
I = 8.75 sin (200Ï€et/57.3) A
Here, "I" represents the current in amperes (A).
"Ï€" 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 (200Ï€(2)/57.3) A
I = 8.75 sin (400Ï€/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.
