A joule
Watts are units of power. Joules are units of energy. They are not the same. One watt is one joule per second.
1 watt is a unit of power that represents the rate at which work is done or energy is consumed. It is equivalent to one joule of energy per second. It is commonly used to measure the power output of electrical devices.
You should think of "watt" as a rate or speed ... it's the speed of using energy, but instead of speed, it's called "power". 1 watt means that 1 joule of energy is being used every second. 1 watt-second means the amount of energy used in one second, when it's used at the rate of 1 watt. In the last paragraph, we just said that this is 1 joule of energy. "Kilowatt" is also a rate at which energy is used. It's 1,000 joules per second, or 1,000 watts.
An electric bulb rated at 40 watts does 40 joules of work in one second. This is because the watt is defined as one joule per second. Therefore, a 40-watt bulb converts 40 joules of electrical energy into light and heat every second it is on.

No. One watt is one joule/second.
1 Joule is 1 Watt-Second. 1 Watt Hour is 3600 Watt-Second or 3600 Joules. 400 Watt-Hours is 1440000 Joules.
No. 1 watt = 1 joule per second 1 watt-second = 1 joule 1 kilo-joule = 1,000 joules
The watt, which is equal to 1 joule/second.
1 Watt = 1 Joule / Second = 1 Newton-meter / Second.
The unit that represents 1 J of work done each second is the watt, symbolized as W. The watt is defined as 1 joule of work done or energy transferred per second.
1 watt means 1 joule/second. To produce 1 watt means that every second, 1 joule of energy is produced.
Watt is a unit of power, not a unit of energy. Joule is the SI unit for energy; Watt means Joule/second. So, the "per time unit" is already implied. Saying "watt per second" or "watt per hour" would be completely wrong. The power is simply "900 Watt".
One joule per second equates to:One watt or,0.00134 electric horsepower or,3.412 BTUs per hour.
1 watt is equal to 1 joule per second. This means that 1 watt of power equals 1 joule of energy expended over a period of 1 second.
About one watt of heat. A 1500 watt heater will warm a 400 square foot room in the winter months. one watt is a very small volume of heat.AnswerHeat is measured in joules. A watt is equivalent to a joule per second. So your answer is that a watt produces one joule of heat every second.
1 joule per second = 1 watt
