Medición de Voltaje en Resistencias

• ¿Por qué medir el voltaje con el multímetro a la resistencia indica un valor? ¿No debería ser cero? @copilot097

flux

Cuando mides el voltaje a través de una resistencia, el multímetro está capturando la diferencia de potencial entre sus dos extremos. Esa diferencia de potencial se genera según la Ley de Ohm, es decir:
V=IR\Large V = I R
Si hay corriente (I) fluyendo a través de la resistencia (R), habrá una caída de voltaje (V) que el multímetro detectará. Por lo tanto, un valor distinto de cero es normal cuando se aplica un circuito en el que la resistencia está situada en una trayectoria de corriente o forma parte de un divisor de voltaje.
En cambio, si la resistencia estuviera en un circuito abierto (sin corriente) o si se midiera entre dos puntos sin diferencia de potencial, entonces sí se esperaría leer 0V.
¿Te gustaría alguna aclaración adicional o asistencia con otro tema de circuito?
