he joule is the unit of energy in the International System of Units, also known as SI. It measures heat, electricity and mechanical work. It was named after English physicist James Prescott Joule. See the related links for more information.
The joule is a derived unit equivalent to a newton-meter, or a kilogram-meter squared per second per second.
A joule is also:
- A unit of electrical energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for a period of time of one second.
- A unit of energy equal to the work done when a force of one newton* acts through a distance of one meter.
[* In the meter-kilogram-second (MKS) system, a newton is the unit of force required to accelerate a mass of one kilogram one meter per second per second, equal to 100,000 dynes. The unit is named after Sir Isaac newton.]

How much electrical energy does a 100W lamp use in 1 second?
Watts measure power. Energy is measured in joules and is the product of power and time. 1 joule = 1 watt for 1 sec Energy used in the example = 100 x 1 = 100 joules
The unit most commonly used for measuring electrical energy consumption is the?
While the SI unit - and therefore, the recommended unit - for energy is the joule, energy used in households is more commonly measured in kWh. Since a joule is a watt-second, a kWh (kilowatt-hour) is equal to 3,600,000 joules.
