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.
