Definición
La unidad de resistencia eléctrica del SI, definida como la resistencia entre dos puntos cuando una diferencia de potencial de un voltio impulsa una corriente de un amperio (1 Ω = 1 V/A).
Explicación
Named after Georg Simon Ohm, who formulated Ohm's law (V = IR). A standard LED circuit resistor is typically 220–470 Ω; a human body's resistance ranges from 1,000 Ω (wet skin) to 100,000 Ω (dry skin). Resistors in series add directly: two 100 Ω resistors in series equal 200 Ω.
