'Power' is a rate; it simply tells us how much energy is being consumed per unit time. In SI, a 'watt' is a special name given to a 'joule per second'. So a 10-W lamp is consuming energy at the rate of 10 J/s (joules per second).
It is incorrect to say that 'power flows'. It's energythat 'flows', power simply tells us how quickly energy flows. You can think of 'power' as being equivalent to 'speed'; you would never ever say that 'kilometre per hour' flows, so you can't say that a 'watt' flows!

Could batteries light a light bulb?
Yes, even a potato can light a light bulb. Yes. If the batteries match the voltage of the bulb, they can light it. Flashlights have bulbs and batteries that power them. If you mean a household light bulb, then you'd need many batteries in series (80 of the 1.5 volt batteries).
How many hours did Edison light bulb stay lit?
66
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
How many wires are normally connected to a double filament light bulb?
5
How many Irish men does it take to change a light bulb?
It takes 201. 1 to hold the light bulb and 200 to turn the house.
How many joules are saved by a energy efficient light bulb?
there are 100 joules in an energy efficient light bulb 75 joules go towards the light and 25 joules go towards the heat
Does a 150 watt bulb do 150 joules of work?
Every second a 150 Watt bulb converts 150 Joules from electricity into heat and light. The number of Watts tells you how many Joules pass per 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).
How many lumens does a 150-watt light bulb produce?
A 150-watt light bulb typically produces around 2600-2800 lumens.
How many joules does a 40 watt ight bulb convert in 10 seconds?
Four Hundred Joules
How many lumens does a light bulb with a power consumption of 150 watts produce?
A light bulb with a power consumption of 150 watts typically produces around 2600 to 3000 lumens.
How many joules of energy does a 100 watt bulb require each second?
With current (as of 2013) technology, from best to worst efficiency, the light bulbs are basically:LED light bulbs (most efficient)Fluorescent lightsThe old-fashioned incandescent lights (worst)
How many joules does c4 produce?
A gram of C4 explosive produces approximately 6,700 joules of energy when detonated.
How many parts are there to a light bulb?
their are 8 parts to the light bulb
How many apples does it take to light a light bulb?
It would take a lot of apples to generate enough electricity to light a light bulb. Apples can produce a small amount of electrical current through a process called oxidation, but it would likely require hundreds or even thousands of apples to power a light bulb.
If the light bulb from number 10 radiates 100 watts times 100 joules per second of photons. How many photons per second are radiated?
To find the number of photons being radiated per second, you need to calculate the energy of each photon first. Since the light bulb emits 100 watts (100 joules per second), and each photon has an energy of about 4.86 x 10^-19 joules for visible light, you can divide the total energy emitted per second by the energy of each photon to find the number of photons emitted.
How many light bulbs to light a big light bulb?
It depends how big the light bulb is to be honest
