One kilowatt-hour (kWh) is the amount of work or energy generated when one kilowatt of power is supplied for a time of one hour. A kilowatt-hour is the unit of energy used by power companies when figuring your electric bill. Determine the number of joules of energy in one kilowatt-hour.
To determine the number of joules of energy in one kilowatt-hour, we need to convert kilowatt-hours into joules.
First, let's convert kilowatts to watts. Since one kilowatt is equal to 1000 watts, we can say that one kilowatt-hour is equal to 1000 watt-hours.
Next, let's convert watt-hours to joules. Since one watt-hour is equal to 3600 joules, we can multiply the number of watt-hours by 3600 to get the number of joules.
Therefore, one kilowatt-hour is equal to 1000 watt-hours, which is equal to 1000 x 3600 = 3,600,000 joules.
Therefore, there are 3,600,000 joules of energy in one kilowatt-hour.
