Actividad 5: Cálculo de Costo de Energía Eléctrica

Si un aparato de 100 W se utiliza durante 4 horas y el costo de la electricidad es de 0.10 USD por kWh, ¿cuál es el costo total de su funcionamiento durante ese tiempo? Completa los espacios con las palabras correctas.

Consumo de Energía

Answer :

To determine the total cost of operating a 100-watt device for 4 hours with an electricity rate of 0.10 USD per kWh, we can follow these steps:

1. Convert Power Consumption to Kilowatt-Hours:
- Power of the device: 100 watts.
- Convert watts to kilowatts: [tex]\( \frac{100 \text{ watts}}{1000} = 0.1 \text{ kilowatts} \)[/tex].

2. Calculate Energy Consumption:
- Use the device for 4 hours: [tex]\( 0.1 \text{ kilowatts} \times 4 \text{ hours} = 0.4 \text{ kilowatt-hours (kWh)} \)[/tex].

3. Calculate the Total Cost:
- Electricity cost is 0.10 USD per kWh.
- Total energy consumption is 0.4 kWh.
- Total cost: [tex]\( 0.4 \text{ kWh} \times 0.10 \text{ USD/kWh} = 0.04 \text{ USD} \)[/tex].

Thus, the total cost of running the device for 4 hours is 0.04 USD.
