100 Joules / sec = 100 Watts
Example of 100 Watts:
(Taking g as 10 (m/s)/s)
Lift 10 kg 1 metre in 1 second
Power = energy change / time = mgh / 1 = 100 / 1 = 100 Watts

How does watt and joule relate?
The Joule is a unit of energy, while the Watt is a unit of power. Joule is the alternate name for a Newton-meter of energy, and Watt is the alternate name for a Newton-meter per second of power. This means that one Watt is one Joule per second; a 100-Watt light bulb converts 100 Joules of electrical energy every second into heat energy and light energy.
How dou you convert joules to watts?
Joule is a unit of energy, watt is a unit of power. Power is energy per time unit. In a way, those are incompatible units, but if you know in what time you spend a certain amount of Joule, you can convert to Watt, and vice versa. For example, if you use 200 Joule in 2 seconds, that is 200/2 = 100 Joule/second, or 100 Watts. Or, if a light-bulb uses 35 Watts, that is 35 Joules every second, so in an hour it will use 35 x 3600 = 126000 Joules, or 126 KJ.
What is gravitational potential energy for 200 n and 100 meter cliff?
GPE = mgh = (mg)*h = 200*100 = 20,000 Joules.
The average weight of a second grader?
average.. is about 100.
How much energy does it take to raise 100KG by 1 meter per second?
The amount of energy required is found by the following equation E=mgh Energy=mass*gravity*height m=100Kg g=9.81m/s^2 (Standard gravity on Earth) h=1.00m so, E=(100)*(9.81)*(1.00)=981J The second is irrelevant when determining energy, it would take 981J to lift it in 1 second or in 1 year. However, power takes time into consideration as it is the rate at which work is performed, P=E/t Power=energy/time =981/1=981W 100 Joules I believe. = =
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.
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.

The power of a light bulb that converts electrical energy at a rate of one hundred joules per second is?
1 joule is the energy equal to 1 watt for 1 second.100 joules = 100w for 1 second.A 100 watt light bulb converts 100 joules of electrical energy into heat and light every second.Only about 1% of this is useful light, the rest is wasted as heat.AnswerPower is defined as the rate of doing work. As work is expressed in joules (J), it follows that power is measured in joules per second (J/s) -however, in SI, this is given a special name: the watt (W).So one joule per second is exactly equivalent to one watt. Therefore, 100 J/s is exactly equivalent to 100 W.
How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
What mechanical work can be done using 100kW energy?
100 kW is not an energy, it is a power. It is the same as 100 kJ/sec (100,000 joules/second. The 100 kW - or 100 kJ/second - can be converted to 100 kW of mechanical power - or less, depending on the type of energy, and how much is wasted.
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
How long can you operate a 100 W bulb with 1 Joule of energy?
The light bulb dissipates 100 watts = 100 joules per second.1 joule lasts 0.01 second.
How much energy every second would a 100 watt light bulb use?
100 Joules = 100 watt second = energy1 joule = 1 watt second
Is it true that energy is measured in joules?
Yes, but it might be confusing to some, because it is also the unit for work. To do 100 joules of work, you need 100 joules of energy. See related link for more detail.
100 joules of heat plus to system of 60 joules of work?
internal energy change in words is the difference between the added energy and the original energy 100 - 60 = 40J
