A 12-volt circuit: the current it draws, the power it burns
engineering
Ohm's law ties voltage, current and resistance; the power law says how much heat that makes. 12 V across 6 Ω draws 2 A and dissipates 24 W — the power line standing on Ohm's. Worked & sealed by the engine — V = I·R → 12 = 2·6 · P = V·I = 12·2 = 24 W. [HOLDS; open the seal to re-check.]
