What energy is produced by a 60 W light bulb lit for 4.3 hours?

first you have to conver 4.3 hours into seconds, which is 15480seconds and then you multiply that by the power which is 60 W, which then you get 928800 Joules

What is the least efficient kind of light bulb?
It is the Incandescent light bulb. Most of the energy are lost as heat
Is a light bulb a mechanical energy?
No. It converts electrical energy into light and thermal energy only.
What happens to the energy wasted in a light bulb?
electircal or photo electrical energy. Photons are shot across from panel to another panel this sparking back and forth creates the light you see.Answer: Electricity is the energy input into a light bulb. It either heats afilamanet to produce heat and light, r excites the gas contained in the bulb (in flluorescent tube) to emit visible light directly or emit UV light which interacts with a phosphor coating in the tubes to emit light.
How many hours did Edison light bulb stay lit?
66
Is it correct to say that an incandescent bulb and a light stick use the same form of energy to create light Why or why not?
No. One is chemical energy, the other is electrical energy.
What is most of the energy produced by a light bulb?
Most of the energy in a light bulb is heat energy.
What form of energy had been produced when we are using a light bulb?
Heat and Light energy
What energy is produced from the light bulb?
Light, of course, since that's what the light bulb is designed to produce. There is also waste energy, as heat, and (to a small extent) as sound.
What are the types of energy produced by a burning light bulb?
Light , which is useful Heat , which is NOT useful.
Where does the energy for a light bulb come from?
it come from the energy source in the middle of the light bulb he clearly asked what type of energy is it?!
If electrical energy goes into a light bulb what useful energy comes out?
The useful energy that comes out is light energy. Heat energy is also produced but is not useful
How you can calculate how much energy is used by a light bulb?
from its power if it is 100 watt so it produces 100 joule per second but this includes all energy produced by the lamp (light/heat energy) Their is a formula E=h x v, E=energy, v=frequency, and h=the constant I think
When electricity runs through light bulb what other type of energy is produced?
Light, heat, sometimes sound.
What powers a light bulb?
The energy used by a lightbulb in kWh can be calculated from the voltage across the bulb, the current through the bulb, and the number of hours of operation of the bulb. energy = voltage * current * hours / 1000
What type of energy is produced with a battery wires and a bulb?
The battery produces electrical energy. If the light bulb is connected between the terminals of the battery, then the bulb will change the electrical energy into heat, and if you're lucky and you have the correct voltage, also maybe some light.
Can you use a light bulb for solar power?
If you mean could you use the light from a bulb to energize a solar array or photovoltaic cell, the answer is yes. However the energy to run the bulb would exceed the energy produced by the array so you would have a net loss of energy in such a system.
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.
