Regular light bulbs work as heaters while giving light.

More than half the power used by Incandescent Bulbs goes to heating your room, rather than lighting it.

Most household electricity supplies come from rainwater flowing downhill (Hydroelectricity), or boiling water to drive steam turbines with coal, oil or nuclear heaters.

Fluorescent lights emit a narrower range of light wavelengths, using their input power more efficiently.

LED lights emit on an even narrower range of light, so are brighter within their colour.

Lasers can be even more efficient, but they are often so focussed and one coloured that they are not very useful for household lighting.

Global warming can be considered one the effects of light bulbs. Many people had a lack of sleep when they were invented because their offices or factories were able to open though it was dark (gas and fire were available to light the dark, but it was expensive)

Do you have a diagram on 9volt battery and light bulb?

Draw a battery and light bulb. Draw a line from the smaller connector on the battery to the bottom of the light bulb, this is positive on both. Draw a line from the bigger connector on the battery to the side of the light bulb,'this is the negative of both. Looked all over and can't seem to find this one.

The switch is not needed.


What will happen if you try to complete a circut by joining the glass of a light bulb to the batttery?

The glass of the light bulb is not conductive, so the circuit would not be completed. You would need to join the wires to the positive and negative contacts on the base of the bulb for the circuit to work.


What happens when you connect the battery's negative side to the ground with a light bulb will it light up?

Nothing happens at all, unless there is a complete conducting path back to the battery's positive side. Once you have that, current will flow, and the light bulb may light up.
