How much power in watts will an led bulb consume if its energy is 6 joules?

Joules (energy) are not equivalent to Watts (power).
If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.
Multiply the Watts by the seconds to find the Joules.

You do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.

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
How many watts are in defibrillator?
The AED output is in joules (J); an energy output. Energy is an Amp Ohm divided by time. Although AED's may vary on their output, depending on numerous criteria, some AED's will shock at 200J, then 300J, then 360J.
How many joules does A 100 watt light bulb consume in 24 hours?
You need to understand the difference between power - as in watts - and energy - as in Watt hours. Watts/kiloWatts only tells you what it's doing at the moment, at that very instant. While Wh/kWh tell you the sum of what it's been doing over a certain time. 1 kW = 1000 w So 100 W / 1000 W = 0.1 kW As soon at the light is turned on, the lamp starts to use energy at the rate of 100 W = 0.1 kW If you leave it on for 24 hours it will have used up 0.1 x 24 = 2.4 kWh
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.
How many watts are consumed by a starter motor if it draws 150 amperes at 10 volts?
Power (W) = Current (I) X Voltage (V)Therefore a system drawing 150 Amps at 10 VoltsP=150X10P=1500 wattsor 1.5 kWAnswerWithout wishing to be pedantic, power is not 'consumed' by a load such as a starter motor. Power is simply a 'rate', the rate at which the load is consuming energy. You cannot 'consume' a rate, therefore, you cannot 'consume' watts! So your question should be rephrased to ask 'What is the power of a starter motor?', or words to that effect.
What is the conversion from joules of energy to watts of energy?
There is no conversion, as joules measures energy and watts measures power -two different quantities!
A couch potato might consume 6 million Joules of energy in a day What is this rate of energy consumption in watts?
Rate of energy= 69.4 watts.
How many watts are 4680000000joules?
Watts are a measure of power, Joules are a measure of energy. The energy is equal to the power times the time. So if you have a power of 5 watts running for 7 seconds, that is 5x7 Joules of energy, or 35 Joules. Looked at another way, power measures how fast energy is converted. So 35 Joules converted in 7 seconds would be 5 watts of power, but it would need 35 watts to convert that energy in 1 second.
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 is the relationship between watts and energy output?
Watts is energy output. Watts is joules per second. Joules is energy.
What is the speed at which energy is transfered?
That is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = Watts
How long could 90 Js of energy light a 40 Watt light balb.?
Power (watts) = Energy (joules) / time (seconds). Thus, Time (seconds) = Energy (joules) / Power (watts) = 90J / 40W = 2.25s
What is power at which energy is transferred?
Power is energy / time. In SI units, joules / second, also known as watts.
How much energy does a 100-w light bulb use in 10 s?
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
What is a quantity that measures the rate at which work is done?
Work is usually measured in joules, which are a unit of energy. Work/time is called power and is usually measured in Watts (joules/second) other common units of power include Horsepower and ft*lbs /sec. in short, is is power, which is measures in watts.
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.
What is the watts equivalent of 231000 joules?
231,000 joules is an amount of energy, while watts are a measure of how fast energy is used or converted. 231,000 joules could be used by 1 watt running for 231,000 seconds, or 231 watts running for 1000 seconds, etc. Energy = power x time, so 1000 watts for 231 seconds is an amount of energy equal to 231,000 joules.
