Answer

La respuesta correcta es **C. Ambos A y B**.<br /><br />La relación entre voltaje (V), corriente (I) y resistencia (R) se describe mediante la Ley de Ohm: V = I * R.<br /><br />* **Técnico A:** Si la resistencia permanece constante y el voltaje aumenta, la corriente también debe aumentar para mantener la igualdad en la ecuación. Por lo tanto, el técnico A tiene razón.<br /><br />* **Técnico B:** Si la resistencia permanece constante y el voltaje disminuye, la corriente también debe disminuir. La corriente eléctrica es el flujo de electrones libres, por lo que una disminución en la corriente significa una disminución en el número de electrones libres que fluyen a través del circuito. Por lo tanto, el técnico B también tiene razón.<br />
