Ohm's law and power
Enter any 2 of U, I, R, P — the rest is computed
Known values
The formula wheel: U = I·R, P = U·I, P = I²·R, P = U²/R. Any two quantities uniquely determine the rest. Practical: a 2 kW kettle at 230 V draws ~8.7 A — a 16 A breaker handles it, but add a washing machine and it's borderline.
