The RMS Current Calculator calculates the root mean square value of an alternating current based on its peak current. RMS current represents the effective value of an AC signal, equivalent to the direct current that would produce the same heating effect in a resistor. Using the formula Irms=Ip/2I_{rms} = I_p / \sqrt{2}Irms​=Ip​/2​, where IpI_pIp​ is the peak current, this calculator provides a quick and accurate result in amperes. It is commonly used in electrical engineering, power analysis, and circuit design to determine the real power capability and efficiency of AC systems.
