60-watt light bulb in jouls?
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
How much energy does a sixty watt light bulb use to yield light?
It takes 60 watt-hours. Same as lighting a 1-watt bulb for 60 hours; or 60 bulbs of 1 watt each for 1 hour. You get the idea.Notice the units: watt-hours, not watts. Watt is a unit of power, watt-hour is a unit of energy. 1 watt-hour = 0.001 kWh (kilowatt-hour) = 3600 joules = 860 calories = 3.4 BTU.
What uses more electricity a lit light bulb or an empty socket of the same rating switched on?
When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
How do you prove that it is the wattage and not the physical size of a light bulb that matters for energy use?
You can prove it by using an energy monitor that measures the actual energy consumption of the light bulb. The wattage directly correlates to the amount of energy used by the bulb, regardless of its physical size. A higher wattage bulb will consume more energy than a lower wattage bulb, even if they are of the same physical size.
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.

What is wh on a battery?
WH means 'Watts per hour'.An example: A light bulb which is 20Watts, is run for 2 hours, which equals to 40Wh.This means 40Watts are used in an hour.Does that kinda make sense?An actual definition is:Wh - Watt-hour, measurement of the total energy of the battery.Hope this helped! :]

What type of energy is when you plug in a light bulb?
To plug it in, you use your muscle energy. When current flows through the bulb,electrical energy converted to the heat and light energy in the bulb.

What is the Electrical power for a lightbulb?
The power rating for a light bulb (like "40 W") tells how much electrical power the light bulb uses. All of the power used by the bulb is either converted into light or heat. In an incandescent bulb, most of the energy becomes heat. In a fluorescent bulb, more of it becomes light.
What are the energy conversions used in a lamp?
A lamp converts electrical energy into light energy. The electrical energy powers the bulb, which generates light through a process called incandescence or fluorescence, depending on the type of bulb used.
What uses more electricity a lit light bulb or an empty socket of the same rating switched on?
When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
How much energy used in a light bulb every second?
That depends a lot on the type of lightbulb. Check the number of watts on the lightbulb - watts means joules / second. An old-fashioned incandescent lightbulb might use in the range of 40-100 watts (joules/second); 100 watts for the brighter ones. On the other hand, a fluorescent lightbulb uses around 40 watts for the brighter ones, and a LED lightbulb uses even less.

A higher wattage bulb will consume more energy than a lower wattage bulb, even if they are of the same physical size.
What is the energy used to brighten a bulb?
It goes from solar energy to electrical to light/&heat

How much of the electrical energy used to light an incandescent bulb is converted into light energy?
Only about 10% of the electrical energy used to light an incandescent bulb is converted into light energy. The rest is mostly given off as heat.
