Ohm's Law states that voltage (V) equals current (I) multiplied by resistance (R): V = IR. It is the foundation of electrical circuit analysis. Power (P = VI = I²R = V²/R) describes the energy converted per second.

Pro Tip
Most household circuits are 15A (US) or 20A. A 15A/120V circuit can handle up to 1,800W. Running appliances above this trips the circuit breaker.

Did You Know?
Georg Ohm published his law in 1827. It was initially rejected by scientists — the Royal Society awarded him the Copley Medal 14 years later once it was proven experimentally valid.
