1. How much will it cost to run a 1500-watt swimming pool heater continuously for 5 hours if the utility company is charging 10 cent per kWh?
Please Help Me!!
kW =1500/1000 = 1.5.
kWh = 1.5 * 5 = 7.5.
Cost = 7.5 * 10 = 75 Cents.
To calculate the cost of running a 1500-watt swimming pool heater for 5 hours, we need to follow these steps:
Step 1: Convert the power consumption from watts (W) to kilowatts (kW):
Since 1 kilowatt is equal to 1000 watts, we divide the power consumption (1500 watts) by 1000 to convert it to kilowatts:
1500 watts / 1000 = 1.5 kilowatts (kW)
Step 2: Calculate the total energy consumed (in kilowatt-hours - kWh):
Energy = Power x Time
Energy = 1.5 kW x 5 hours = 7.5 kilowatt-hours (kWh)
Step 3: Calculate the cost of energy:
To find the cost, we multiply the total energy consumed by the cost per kilowatt-hour:
Cost = Energy x Cost per kWh
Cost = 7.5 kWh x $0.10/kWh = $0.75
Therefore, it will cost $0.75 to run the 1500-watt swimming pool heater continuously for 5 hours if the utility company is charging 10 cents per kilowatt-hour (kWh).
