The energy used by a 40W bulb in one second is 40 Joules. This is because power is defined as the rate at which energy is transferred or converted, so if the bulb consumes 40W of power in one second, it uses 40 Joules of energy in that time period.
A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts. Watts means joules per second (joules / second), or equivalently, joules is watts times seconds.A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to 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.
Momentum does not have the same units as the others. Kinetic energy is measured in joules, potential energy in joules, work in joules, but momentum is measured in kilogram meters per second (kg m/s).
A 600 watt drill uses 600 joules of energy every second because power is calculated as energy used per unit of time.

The rate of energy transfer is called power. It represents how quickly energy is transformed or transferred from one form to another. Power is measured in watts (W) or joules per second (J/s).
An 11-watt bulb uses 11 joules of energy per second.
The rate of energy transfer - any type of energy transfer, including this specific case - is called the power. The SI unit is the watt, which is equal to joules/second.
Energy / time is known as power. In SI units, time is measured in seconds, energy in joules; the unit for joules / second has the special name watts.
Electron flow is current, or coulombs per second. Electron potential is voltage or joules per second.
You can divide any unit of energy by any unit of time; but the standard SI unit is Joules / second, and has the special name "Watt".
To convert electric potential energy (eV) to meters per second (m/s), you can use the formula: 1 eV 1.602 x 10-19 joules. Then, you can use the formula for kinetic energy: KE 0.5 m v2, where KE is the kinetic energy, m is the mass, and v is the velocity in meters per second. By equating the electric potential energy to the kinetic energy, you can solve for the velocity in meters per second.
100 joules/second = 100 watts.
100 joules/second = 100 watts.
Power is expressed as joules per second. It is a measure of the rate at which energy is transferred or converted.
