In a 60 watt light bulb how much energy is converted into heat?
What are the uses of Heat energy
How much of the electrical energy used to light an incandescent bulb is converted into light energy?
About 2 %.
What does low energy mean?
low energy is when a product or object does not "consume" as much energy than a normal "object". for instance, an energy saving bulb will use less energy than a normal bulb.
Does the size of the light bulb affect how much energy it uses with wire and a battery?
No, only the resistance of the filament counts (normally marked as "wattage" on the bulb).
Why do you think a light bulb feels warm?
A light bulb is designed to take electrical energy and radiate it as electromagnetic energy.It would be nice of all of that energy came out in the form of light, but that has never been accomplished yet. An incandescent light bulb ... the original kind ... radiates much more heatenergy than light energy. In other words, an incandescent light bulb works much more efficientlyas a heater than it does as a source of light.
When 60 W means that W joules of energy are transferred into the bulb each second. In use how much energy is given out by the bulb each second?
The light bulb will use electrical energy at the rate of 60 W (60 J/s), and it will emit that energy, also at the rate of 60 W.Note that in any real light bulb, only part of the energy is emitted as visible light. The remainder is mainly heat.
What happen to an electric current after it passes through each bulb?
There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.
If you add an extra battery to a circuit containing a bulb how will this affect the bulb?
The bulb becomes brighter unless it is too much till it shot-circuits.
How much energy does a normal light-bulb make in comparison to a colored one?
They are the same light bulb, so they are the same. The colored bulb has coloring applies on its outside surface. They do not make energy, they use energy.
How much does it cost to run a 100 watt bulb per hour?
That bulb is 100 watts or 0.1 kilowatts so it uses 0.1 kilowatt-hour of energy each hour, which costs about £0.015
How much energy do you save with 10 light bulbs off?
That depends on the power used by each light bulb. Look at the specifications for a specific light bulb, then multiply the power by 10. Note that energy = power x time; that is to say, the energy spent by a light bulb depends on its power, but also on how long you keep it on. Specifically, watts = joules x seconds.
In a 60 watt light bulb how much energy is converted into heat?
What are the uses of Heat energy
How much of the electrical energy used to light an incandescent bulb is converted into light energy?
About 2 %.
Different color light bulb affect how much energy it has?
No, Colored light bulbs holds the same amount of energy a regular light bulb holds.
How much energy does a 5 watt light bulb use off?
A lot
What do you need to know to calculate how much energy light bulb uses?
You should be able to read the power off the bulb or its packaging.
How does the brightness of the bulbs in the two circuits compare?
ANSWERwhen two bulb are connected in series their will not be any changeANSWERWhat other bulbs? This question doesn't make sense.Perhaps you are thinking of this: with two bulbs in series, each bulb only gets 1/2 of the energy (or voltage) that a battery makes available, so each bulb is much dimmer than just one bulb attached to the battery would be.
