How it works

Enter any two compatible electrical values to derive all four for a purely active DC load. Zero-resistance edge cases are handled explicitly.

The custom engine selects a safe path among V = IR, P = VI, P = I²R and P = V²/R.

Examples

12 V and 6 Ω{"resistance":{"unit":"ohm","value":6},"voltage":{"unit":"V","value":12}}
