What is this RMS Current Calculator?

The RMS Current Calculator helps users calculate the root mean square (RMS) value of an alternating current (AC) from its peak current. By entering the peak current, the tool computes the RMS current, which represents the effective current that produces the same heating effect as a direct current. This ensures accurate understanding of AC behavior, making it useful for students, engineers, and anyone working with electrical circuits.

How to Use:

1. Enter Peak Current (I₀, amperes): Input the maximum or peak current of the AC in amperes.
2. Click “Calculate”: The calculator computes the RMS current using the formula IRMS=I02I_\text{RMS} = \frac{I_0}{\sqrt{2}}IRMS​=2​I0​​.
3. Review Result: The output shows the RMS current in amperes, along with a prompt if an invalid value is entered, helping you understand the effective AC current safely and clearly.
