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
My answer is 2.1A.
I=Imax/sqrt2=2.1 A
To find the rms value of the current in an AC circuit, you will need to use the formula:
I(rms) = I(max) / √2
In this case, the maximum current (I(max)) is given as 3.0 Amperes. Plugging in this value into the formula:
I(rms) = 3.0 A / √2 ≈ 2.12 A
So, the rms value of the current in the AC circuit is approximately 2.12 A.
Therefore, your answer of 2.1 A is close, but the correct answer would be 2.12 A.
