A 60 watt light bulb runs for 5 seconds how much energy does it use?
Hailey Gibbas
That would be 40x60 watt-seconds, also known as Joules, so it's 2400 Joules of energy. 3.6 MegaJoules is equal to one kilowatt-hour, also known as 1 unit.

How much energy will a 100w light bulb convert to light and heat if it is left burning for 1hour?
Power = Energy/time 100W=Energy/360 Seconds Energy = 100/360 Energy ≈ 0.27 Joules
How much of the electrical energy used to light an incandescent bulb is converted into light energy?
About 2 %.
In a 60 watt light bulb how much energy is converted into heat?
What are the uses of Heat energy
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.
How much work does a 100-watt light bulb do when it is lit for 30 seconds?
3000 joules(J)
How much energy does a 95 watt light bulb use in 40 seconds?
The energy is 95 x 40 watt-seconds (Joules).
How much energy will a 100w light bulb convert to light and heat if it is left burning for 1hour?
Power = Energy/time 100W=Energy/360 Seconds Energy = 100/360 Energy ≈ 0.27 Joules
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.
How much heat energy will a 40W light bulb give out in 3 minutes?
Joules = watts x seconds. Just convert the minutes to seconds, then multiply.
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.
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 of the electrical energy used to light an incandescent bulb is converted into light energy?
About 2 %.
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 energy do you save per hour if you replace a 60 W light bulb with a 55 W light bulb?
18,000 J
How much energy does a 5 watt light bulb use off?
A lot
