How many joules of light energy are in 1440 watts of electrical energy?
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.

What is the energy used in one second when a bulb have 40Watts.?
40 Joules, I think, as the formula for Watts is Joules/Second = Joules per second 40 Watts should equal 40 Joules per one second...
How much work can a 500 watt electric mixer do in 2.50 minutes?
The work or energy in Joules is the power in watts times the number of second it runs for. So 500 watts for 150 seconds is 75,000 Joules.
If an object weighing 90 kilograms and moving with a velocity of 20 meters per second has a kinetic energy of 4500 Joules. what is its kinetic energy when the velocity is 32 meters per second?
KE=(1/2)mv246080 Joules
What is the average energy transfer of a TV in joules?
If you look at your television set's nameplate, it will specify its power in watts. A watt is simply a joule per second. So, if your television is rated at, say, 300 W, then it is transferring energy at the rate of 300 joules per second.
What is the rate at which electrical current is converted to another form of energy?
The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.

What is the relationship between watts and energy output?
Watts is energy output. Watts is joules per second. Joules is energy.

What is the rate which electric energy is convert to another type of energy?
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.
What is the energy used every second known as?
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.
How much work can a 500 watt electric mixer do in 2.50 minutes?
The work or energy in Joules is the power in watts times the number of second it runs for. So 500 watts for 150 seconds is 75,000 Joules.
How many joules of energy is consumed if the electrical meter shows 400 units of energy?
The electric meter uses kWh (kilowatt x hours) as units; a Joule is a watt x second. Therefore, a kWh has 3.6 million joules. Just multiply by this number.
How to calculate rate of energy transfer in Joules per second or Joules per minute?
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".
The power of a light bulb that converts electrical energy at a rate of 100 joules per second is what?
100 joules/second = 100 watts.
What is the power of a light bulb that converts Electrical energy at a rate of 100 joules per second?
100 joules/second = 100 watts.
What is the power of light bulb that converts electrical energy at a rate of 100 joules per second?
100 joules/second = 100 watts.
