The watt was named after James Watt. The term watt in electric appliances refers the rate at which energy is generated or consumed and therefore is measured in units (e.g. watts) that represent energy per unit time. An example; when a light bulb with a power rating of 100W is turned on for one hour, the energy used is 100 watt hours (The watt second is a unit of energy, equal to the joule).

How much energy is used by a streetlight per hour?
Yes, that's the question. A 1000 Watt light uses... 1000 Watts. A 500 Watt light uses, you guessed it... 500 watts. It depends on the size of the bulb. ACTUALLY... Watts are a measure of power, Joules are the measure of energy - you can simply convert watts/hour or watts/second to joules but to say that a 1000 Watt light bulb uses 1000 watts is a ridiculous thing to say =D watts are Wh-1 or Ws-1
What kind of amps does a 65 watt light take?
amps equals watts divided by volts.
How many lumens does a 150 watt CFL give off?
A 150-watt light bulb uses energy at the rate of 150 watts, when it's turned on.
What is The electrical power used by light bulbs measured in?
Electrical power is measured in watts (W), just like any other type of power.Power is the rate at which energy is used. Energy is measured in joules (J), though utility bills usually measure energy using kilowatt-hours (kW·h) instead. 1 kW·h = 3,600,000 J.
Amps used by 32 watt fluorescent light bulbs?
If it is a 120volt light, then it is watts / volts. 32 watts / 120 = .2667 amps. <<>> fluorescent lights usually have a power factor around 0.6 so a 32 watt bulb would take around 32/(120 x 0.6) amps or 0.44 amps.

Is a watt a light bulb?
A 60 watt light bulb is a light bulb with 60 watts capacity. When talking about watts, you're talking about the power that is transferred from the appliance to the accessories. Therefore, the light bulb labeled "60 watts" takes 60 watts to light up. A 60 watt light bulb will not be as bright as a 120 watt light bulb.

What does James watt have to do with calculating power?
The SI unit of power, the watt, is named after James Watt, for his contributions to the development of the steam engine. The symbol for watts is a capital W. The watt is a derived unit, equal to 1 joule of energy per second, a rate of conversion of energy. In electricity, 1 watt is 1 ampere at 1 volt (watts = amps X volts).
A 100 watt light bulb produces 8 watt of light what happens to the other 92 watts?
The other 92 watts become heat.
