Ответ:
Responder: 480 vatios
Explicación:
La potencia en un circuito eléctrico am puede expresarse como el producto si la corriente y el voltaje en el circuito.
Potencia = corriente × voltaje
Corriente dada = 4 amperios
Voltaje = 120 voltios
Potencia gastada en el circuito = 4 × 120
Potencia gastada en el circuito =
480 vatios
