one kilwatt/hour (kWh) is the amount of work or energy generated when one kilowatt of power is supplied fr 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.
1KWh = 1000W * 3600s = 3.6*10^6 Joules.
Well, well, well, ready for a shocking joke? One kilowatt-hour (kWh) is the amount of energy you get when you leave a kilowatt running for an hour. It's like the electric payment equivalent of a superhero origin story! Now, to the serious business: let's calculate the number of joules of energy in a kilowatt-hour.
To do that, we need to convert kilowatt-hours to joules. Since there are 3,600 seconds in an hour (trust me, I didn't make this up), we'll use this little conversion factor: 1 kilowatt-hour equals 3,600,000 joules.
So, in a nutshell, one kWh packs a zappy punch of 3,600,000 joules! That's enough energy to light up a room and power a whole lot of hilarious clown pranks.
To determine the number of joules of energy in one kilowatt/hour (kWh), we need to convert the kilowatt/hour unit to joules.
The conversion factor we will use is 1 kilowatt-hour = 3.6 x 10^6 joules. This conversion factor is derived from the definition of a watt (1 watt = 1 joule/second) and the fact that there are 3600 seconds in an hour.
Now, let's perform the conversion:
1 kilowatt-hour = 1 kilowatt x 1 hour
Since 1 kilowatt is equivalent to 1000 watts:
1 kilowatt = 1000 watts
Now, let's substitute the values into our conversion factor:
1 kilowatt-hour = 1000 watts x 1 hour = 1000 joules/second x 3600 seconds = 3.6 x 10^6 joules
Therefore, there are approximately 3.6 x 10^6 joules of energy in one kilowatt/hour (kWh).
To determine the number of joules in one kilowatt/hour (kWh), we need to convert both kilowatts and hours to joules.
1 kilowatt (kW) is equal to 1000 joules per second (J/s). This is because 1 watt (W) is equal to 1 joule per second, and since there are 1000 watts in a kilowatt, 1 kilowatt is equal to 1000 joules per second.
1 hour is equal to 3600 seconds. This is because there are 60 minutes in an hour and 60 seconds in a minute, so multiplying them gives us 3600 seconds.
Now, we can calculate the number of joules in one kilowatt/hour:
1 kilowatt/hour (kWh) = 1 kilowatt * 1 hour
= 1000 joules/second * 3600 seconds
= 3,600,000 joules
Therefore, one kilowatt/hour is equal to 3,600,000 joules of energy.
