A Watt is power. A Joule is Energy. A Joule is a Watt X Seconds.
Watts are units of Power, whereas Joules are units of Energy. Power is Energy in accordance to time: P = E/t . So One Watt of Power is equal to one Joule per second. P=E/t 1 Watt = 1 Joule/ 1 second

How many joules does a 40 watt ight bulb convert in 10 seconds?
Four Hundred Joules
Convert joules to kwh?
To convert Joules to kilowatt-hours (kWh), divide the number of Joules by 3,600,000 (the number of Joules in a kWh). For example, to convert 1,000,000 Joules to kWh, you would divide 1,000,000 by 3,600,000 to get approximately 0.278 kWh.
60-watt light bulb in jouls?
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
What equals 100 watts?
That depends what you want to convert it to. Watt is a unit of power. 100 watts is equal to:0.1 kilowatts100 joules/second
How much is 400 Wh inn Joules?
1 Joule is 1 Watt-Second. 1 Watt Hour is 3600 Watt-Second or 3600 Joules. 400 Watt-Hours is 1440000 Joules.
How long could 90 Js of energy light a 40 Watt light balb.?
To calculate this, we first need to convert the energy from joules to watt-hours. 90 joules is equal to 0.025 watt-hours. Therefore, with 0.025 watt-hours of energy, a 40 watt light bulb would last for approximately 0.000625 hours or 0.0375 minutes.
How much energy will a 1000w stereo use in 1 minute?
energy = power x time.In this case, you can either: * Convert the time to seconds, then multiply. The answer will be in watt-seconds = joules. * Convert the time to hours, convert the watt to kilowatt, then multiply. The answer will be in kilowatt-hours.
What is the equation of converting horsepower to joule?
Horsepower is a unit of power, but joules is a unit of energy. To convert horsepower to joules, you need an additional time parameter. One horsepower is about 745.7 watts. So a horsepower-hour is 745.7 watt-hours. One watt-hour is 3600 joules. A horsepower-hour is then 745.7 times 3600 = 2684520 joules.
What is 6 million joules in watts?
'Joule' is a unit of energy, whereas 'watt' is a unit of power, which means the rate of using energy. The two units measure different quantities, and neither one can be converted into the other one.
How many joules are in 746 watt-seconds?
1 watt-second = 1 joule...746 watt-seconds = 746 joules(746 watts is an interesting number, and I'm curious to know how it wasselected to be the number in the question. 746 watts = 1 horsepower.1 horsepower = 746 joules of energy per second.The number is easy to remember: The mainsail on the Santa Maria developed2 HP in a fresh breeze during Christopher Columbus' first voyage in 1492.)
How do you work out the number of joules of wasted energy in a TV?
To calculate the wasted energy in a TV, you would multiply the power consumption of the TV (in watts) by the time the TV is left on (in hours). This will give you the energy consumed in watt-hours (Wh). To convert watt-hours to joules, multiply by 3600 (since 1 Wh = 3600 joules).
How many joules are in 100 watts?
There are 100 joules in 1 watt-second, so in 1 second, there would be 100 joules per watt. Therefore, in 100 watts, there would be 10,000 joules.
