Ohm's Law Calculator

This tool calculates electrical values using Ohm's Law formulas. Use it to solve for voltage, current, resistance, or power when you know two values. • Choose one of four calculator sections: Calculate Voltage, Calculate Current, Calculate Resistance, or Calculate Power • Enter the two known values in the input fields using your keyboard • Click the corresponding button (GET VOLTS, GET AMPS, GET OHMS, or GET WATTS) to calculate the missing value • Results appear automatically in the output fields below the button • The tool also calculates circuit power as a bonus when applicable • Use standard units: volts for voltage, amps for current, ohms for resistance, watts for power • Clear input fields manually to start new calculations • All calculations happen instantly when you click the calculate button
