Ohms Law Calculator

Solve voltage, current, or resistance and compute electrical power.

Ohms Law Calculator helps you Solve voltage, current, or resistance and compute electrical power. Use it to solve technical problems quickly when you need accurate intermediate values and final outputs for class, lab, or engineering work. The form is specific to this tool and captures inputs like Mode, Voltage (V), and Current (A), so required data is explicit before you run it. After running, review sections like Ohm's Law Inputs and Result to interpret results and verify they fit your real-world constraints. Save the exact inputs together with the result so teammates can reproduce and audit the output later.
