investigate on using a battery to light a bulb?

isn't that what a flashlight is?

make a solar cell that will light up a lightbulb. Figure out how by doing an internet search

I suppose it should not be a problem.  Only the high voltage should let the bulb fail.  check the voltage rating of the bulb.  The input voltage should not be higher than the voltage indicated in the bulb.

The battery has two terminals, one positive and one negative, with two different types of metals.  Floating inside the battery is also a supply of acid, which scientists would call an electrolyte.  This acid keeps the electrons flowing between the positive and negative terminals all the time.\n\nWhen you set up a wire loop, one end is connected to the positive terminal and the other is connected to the negative terminal.  The free electrons inside the battery like to flow from the positive down to the negative terminal.  Now they have a way out of the battery through the wire.\n\nThe electrons flow through the wire and anything else connected to it, like a small lightbulb.  Some of the electrons are used to make the filament inside the lightbulb glow red hot.  The rest of the electrons continue around the loop and end up at the positive terminal of the battery again.  This process keeps going until either almost all of the electrons are used up in the lightbulb (the battery is 'dead') or the circuit is broken.

The light-bulb has a tungsten filament, which has electrical resistance.  The voltage applied across the resistance causes a current to flow.  The value of the current is: I = V/R, where I is the current in amps, V is the voltage in volts, and R is the resistance in ohms.  The current flowing through the resistance causes it to heat up--it dissipates power.  The power is: P = I*V, or P = R*I^2, where the power is in watts.  MOST of that power produces heat; in an incandescent bulb only a little goes into light.  Power, incidentally, is energy per unit time.  Watts are Joules/sec, where the joule is the SI standard unit of energy.\n\nAs for the motors, connect them in parallel.  They will each receive the same voltage, and each will draw the amount of current it needs.

Light bulb uses light waves.

Sure they can be useful.  If you're camping where you don't have access to electricity, for instance.\n\nThere are problems of course.  A bright flashlight uses a lot of power and there isn't enough surface area for solar cells to capture much energy throughout the day.  So you get a few minutes of use from a whole day of charging.  The newer LED flashlights go a long way to fixing that, though.  And usually it's not a problem because you don't usually need flashlights every night for long periods of time.\n\nAlso you really would want to charge the flashlight outdoors because there isn't very much energy in indoor light.  Sure it's enough to charge a tiny calculator battery, but flashlights need a lot more.  But leaving it outdoors exposes it to the heat/cold/rain/snow/wind/thieves.\n\nDon't store it in the toolbox. :)

Your question is not clear at all, but let me guess a little.\n\nAre you asking for the function of each component in the circuit ???\n\nIf so, light bulb will be the load.\nConductor is the mean for the current to flow.\nswitch, is for closing or opening the circuit\ninsulation, to keep conductors to short the circuit.\nmeter, to measure the voltage or current or power being used at some time.\nbattery is the power source to get the circuit to work.\n\nNow I guess I earn 10 points for best and only answer.

If your talking about regular incandescent bulbs in residential lighting fixtures, then its just the filament size and material that produces different levels of brightness.  For a given bulb, if you want to make it brighter/dimmer you can lower the voltage applied to the bulb.  Regular bulbs run on 120 volts.  There are dimmer switches for home lighting that get installed in the wall, but you can also get certain extension cords that have a variable resistor built in to allow you to control the voltage applied to the bulb, thereby affecting the brightness.

Hmmm, curious.\n\nIf the bulb has a filament you can see, then yet, it will almost certain be dimmable.\n\nI cannot see why there would need to be a trasformer in the box, if you try and wore the lamp in series with a 400Watt rated dimmer, th e worst that is likely to happen is you kill the dimmer.\n\nTry and find a bit more about this (make/model/type) and pop up another question, we can then give better feedback

The lower the resistance of the bulb, the more power it will consume.

An L.E.D. light can run 200 hrs on a set of batteries, but isn't terribly bright.\nA Xenon lamp is Extremely bright, but kills batteries fast.\n\nYou can get either one for ten bucks or so. play it safe...\nGet them both.

You need a circuit called an inverter.  These are available to plug into your 12 V socket in your car.  However, use these with the engine running or you could easily drain your battery.

It sounds like you are creating a basic electrical circuit. with the batteries, wires, bulbs and paper clip you can make either a series or parallel circuit. The light bulbs will light up when you have a complete single loop for series. When you measure the current it should be the same anywhere on the circuit. In a parallel circuit you are splitting the circuits into three or more branches, with one bulb on each side. When measured each branch should be using half the current. You shouldn't have any problem finding a site online that shows this experiment. use keywords, including science experiments for kids. I found the experiment in Reader's Digest,"How Science Works"

Purchase a volts-adjustable power converter, otherwise you will zap your contraption.  Some can plug into a cigarette lighter socket and some can be wired directly to a twelve-volt battery.  Wallmart may still sell them, it's been some years since I've purchased any of em.

Of course not; that would be akin to perpetual motion.  Of the energy used by a lamp, between 5% for an incandescent light bulb to nearly 30% for the best fluorescent tube ends up in usable visible light, and at the other end, the best (and quite costly) solar cells convert 18% of the light in electricity.  So, assuming ALL the light from the best lamp is directed to the best solar cell, you get power back at the rate of 5.4%.  It will get dark pretty quick...

It takes energy to push that current through your lights and appliances, and that's what your paying for. One way to see it is to consider that what comes out the downstream prong is at 0 volts and therefore of no use to anyone. Or, you could just wire all your lamps in series and see how that works!
