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

How many apples does it take to light a light bulb?
I think that the orange and nails light up the light bulb because the acid energy goes through the nails and into the wires connected to the light bulb and powers the light bulb
Who is the first scientist who discover a bulb?
If you are talking about a light bulb that would be Thomas Edison. If you are asking about a flower bulb...I don't know. sorry
How much carbon dioxide does each light bulb emit?
None. Light bulbs do not emit carbon dioxide. The electricity used to power the light bulb may have been produced by a method which emits carbon dioxide (then again, it may not have), but the bulb itself doesn't emit anything except heat and light.
Can i light a light bulb with a battery and a paper clip?
Yes, if your battery has the capacity to match the light bulbs requirements. A 1.5volt "AA" battery cannot supply enough power to light a 60watt bulb. A flashlight that uses a single battery will have a bulb small enough to be powered by a small battery and a paper-clip as a conductor. A low voltage LED may also be used. Touch one end of the battery to one terminal on the bulb, and connect the other end of the battery to the other terminal using the clip. (you may find it helpful to use tape to hold it all together)
If you wired up the circuit with a bulb two batteries and a switch with a thin wire what will happen?

Is a light bulb renewable or nonrenewable?

How many apples does it take to light a light bulb?
I think that the orange and nails light up the light bulb because the acid energy goes through the nails and into the wires connected to the light bulb and powers the light bulb
Where does the energy given off by the light bulb come from?
From the electric current that powers it.
What inside the potato that powers the light bulb?
