Why does a light bulb rated at 100 W not mention a time factor?
Because the "watt" itself is a rate of using energy, equal to 1 joule of energy per second.You can continue to use energy at the rate of 100 watts for as long as you want to,just as you can continue driving at 30 miles per hour for as long as you want to.
How long need to exercise to expend 100 kcal while expending the energy rate of 270 W?
Divide the energy by the power. You'll need to convert kcal to joule first. Then, if you divide joule by watt (which is equal to joule/second), the answer will obviously be in seconds.
What uses more energy a 60 watt light bulb or 18 watt light bulb?
This depends on how long it is being used. The 60 Watt bulb consumes 2.6667 times the power of an 18 Watt bulb, but energy equals power times time. There is also an amount of 'hidden' energy: the energy to manufacture and transport the bulb. This depends on how long it is being used.

How long will a 1 watt bulb operate on a 1 amp hour battery?
Please give the voltage and Ah rating of the battery and voltage rating of bulb.
How much total energy does a 60-watt fluorescent light consume?
Take a look at the units: 1 Watt = 1 Joule/Second A joule is a unit of energy. For example, 1 Joule = .239 calories = Therefore 60 Watts=60 Joules/Second So that means for every second, the light consumes 60 Joules. You must know for how long the light will be on to know how much energy will be consumed.
What are the risks of staring at a 75 watt bulb too long?
Do not operate hazardous machinery or drive a vehicle while doing this.
What is the power out put of one million joules?
A joule is a unit of energy, not a unit of power. A watt is the same as a joule per second, so depending on how long it takes to output a million joules, the power can be very high, or very low.
How long does an energy saving light bulb live for?
not very long.. they are really crap... i have one and its very dim...
How many watts are in a security light with a 40 watt bulb?
If it is a 40 Watt bulb it converts energy at the rate of 40 Watts as long as it is switched on.
How powerful is 10 watts?
A watt is not a unit of energy, it is a unit of power. Power refers to energy transfer per unit time; a watt is one joule/second. For comparison, a fluorescent light-bulb uses somewhere between 15-40 watts; an electric shower may use about 3 kW (3000 watts).
What are examples of heat energy?
Examples of heat energy are as follows: -a bulb turned on for a long time - heat liberated from any burning object
Can you use an energy saving light bulb in a fitting with dusk to dawn sensor?
as long as the sockets for th bulb are the same and it is not a high pressure sodium or metal halide light
