The maximum current in an AC circuit is 3.0 Amperes. What is the rms value of the current in the AC circuit?
0.5 A
2.1 A
3.0 A
4.2 A
I would think D...
3/sqrt2 = 2.1 A
To find the rms value of the current in an AC circuit, you need to know the maximum current and use the formula:
Irms = Imax / √2
Given that the maximum current is 3.0 Amperes, you can calculate the rms value:
Irms = 3.0 A / √2 ≈ 2.121 A
Since the provided answer choices do not include this exact value, the closest option to 2.121 A is 2.1 A. Therefore, the correct answer is B) 2.1 A.
