Ohm's law calculator API

Solve Ohm's law (V = I·R, P = V·I) given any two of voltage, current, and resistance — returns all four quantities including power dissipation. Deterministic EE arithmetic LLMs get wrong. Answers 'what current flows through 4 ohms at 12V','what power does this draw','find resistance from V and I'.
