V on a light bulb means volts. W means watts.

It means that the power consumption of the bulb is 40 watts.

It meas that the bulb uses 25 watts of electric power to run. Different types of bulb produce different amounts of light, with incandescent bulbs producing the least. A bigger proportion of the energy supplied to the compact fluorescent bulb is transferred to light and less wasted to the surroundings as heating.

By whatever do you mean? I mentioned an electric bulb the other day when mine went out. Shoot, you just mentioned it in your Question. Though Thomas Edison built the first working electric light bulb.

Is that the Ω (ohm) symbol you are referring to? An ohm is the unit of electric resistance.

An electrical watt is a measure of power. A 40 watt light bulb uses 40 watts of electrical power. It has a relative measure of twice the light output of a 20 watt bulb and one half the output of an 80 watt bulb. A 40 watt bulb uses 40 Joules of energy each second, or 40 watt-hours of energy each hour. In 1000 hours it uses 40 kilowatt-hours or Units of electrical energy.

The watts means nothing without the voltage.

it will take more than100 watts until the filament reaches operating temperature so perhaps a second to get as low as 100 watts . then 100Watts there after until 300 hours pass then 0 watts if you mean 100Watt hours then the answer is 1 hour and the hour will cost about a penny

Watts are units of power. In simplified terms, power = voltage x current. So if a 120W light bulb is plugged into a 120V standard outlet, it will draw 1 Amp of current (120W = 120V x 1A).

Find out what your electric company charges you per kw hour. Now kw =1000 watts, so say you pay .12 per kw hour. A 100 watt light bulb is 1/10 of 1000 so divide .12 by 10. This would mean you pay .012 cents to run a 100w light bulb per 1 hour. Or .12cents for 10 hours

Do you mean how many watts are used to make hot water? It varies, but a typical home electric hot water heater consumes about 4,500 watts. Industrial hot water heaters might use 20,000 watts or more! I have a little warmer that keeps my coffee warm as I type this, it consumes about 300 watts. Of course it only heats 6 ounces of water....

volts x amps = watts. That mean 15 vamps is 15 watts. If it is 15 amps at 120v then it is 1800 watts.

Not necessarily. More watts does mean more heat, but that does not absolutely equate to a higher temperature. A large professional iron (like a trouser press) will use more watts than a hand iron in order to reach the same temperature, just because it's bigger.

GLS bulb stands for General Lighting Service bulb.

Electric Electric

What do you mean like did he invent the light bulb because if you do mean that then yes he did invent the light bulb

Since the equation for watts is: Volts * Amps = Watts that would mean 12 Volts * 1 Amp = 12 Watts

most hairdryers on low use about 402 watts, and on high about 1440!!!

Number of watts= heat

It isn't clear what you mean with "electric energy" if you don't mean an electric current.

no

Generally more watts on a CB antenna doesn't mean more range. On average, a typical CB antenna takes in 4 watts before damage occurs. Watts is the power source not the range of signal.

The meaning of the term "complete circuit" is a path that is similar to a circle. For example, a very basic complete circuit would be a flashlight. The flashlight bulb is at one end and a battery is connected to the other end of the flashlight. When you turn on the flashlight, the battery drives an electric current to the flashlight bulb, which turns on the bulb. The light will stay on as long as it receives an electric current from the battery. When the flashlight switch is turned off, the complete circuit is broken, and the flashlight bulb goes out (turns off).

if you mean lightning you have to buy it, if you mean electric there is no such thing

No. Amperage is the current flowing down the conductor as voltage is a constant (relatively). As an example- a 120 volt light bulb is of course 120 volts but if it is 60 watts then it will draw .5 amps. a 100 watt bulb will draw around .8 ampsDifferent things.
