This tool calculates the Peak current from its Root-mean-square (RMS) value.
Enter the RMS value and use the drop down menu to select the units (A/mA/uA/nA)
Formula
IPeak = √(2)*IRMS
Where:
- IRMS is the RMS current in Amperes (A)
- IPeak is the Peak current in Amperes (A)
Example Calculation
Suppose you have an RMS current of 1 A and you want to calculate the peak current. Using the calculator above gives an answer of 1.414 A.
Background
What is RMS Current?
RMS current, or Root Mean Square current, is a measure of the effective value of a varying electrical current. It is particularly useful in the context of alternating current (AC) circuits, where the current constantly changes direction and magnitude. RMS values provide a way to express the equivalent direct current (DC) value that would deliver the same amount of power to a load.
