Ohm's Law Extended — science and physics formula calculators
The Ohm's Law Extended calculator solves for resistance, voltage, or current from the other two values, and reports the electrical power in watts alongside every result. It uses V = IR with the power equations P = VI, P = I²R, and P = V²/R. Use it for electronics projects, circuit troubleshooting, a
