Calcula cuanto costara tener encendido toda la noche (8horas) un radiador de 2500w sabiendo que el precio del Kwh es de 15 centi
Varvara68 [4.7K]

Answer:

300 centavos

Explanation:

De la pregunta anterior, se obtuvieron los siguientes datos:

Potencia (P) = 2500 W

Tiempo (t) = 8 horas

Costo de operación =?

A continuación, convertiremos 2500 W a KW. Esto se puede obtener de la siguiente manera:

1000 W = 1 KW

Por lo tanto,

2500 W = 2500 W × 1 KW / 1000 W

2500 W = 2,5 KW

Por tanto, 2500 W equivalen a 2,5 KW

A continuación, determinaremos la energía consumida. Esto se puede obtener de la siguiente manera: Potencia (P) = 2,5 KW

Tiempo (t) = 8 horas

Energía (E) =?

E = Pt

E = 2,5 × 8

E = 20 KWh

Finalmente, determinaremos el costo de operación. Esto se puede obtener de la siguiente manera:

1 KWh = 15 centavos

Por lo tanto,

20 KWh = 20 KWh × 15 centavos / 1 KWh

20 KWh = 300 centavos

Por lo tanto, costará 300 centavos tener un radiador de 2500 W encendido toda la noche (8 horas).
