How can you use a wire battery and a light bulb to test an item to see if it is a conductor of electricity?

I am going to assume you meant Three wires, Battery and Light Bulb. (punctuation and plurals are important)
Hook the light to one post of the battery
Hooked from the light to the item being tested (use the other light connection, not the one connected to the battery)
connect the other end of the test item to the unused terminal on the battery.
Light comes on means it conducts electricity
No Light, it does not.

∙ 14y agoIf the object is conductive, when added to a circuit containing a light bulb and a battery, connected by wire, the light bulb will light up. Depending on how good a conductor the object is, the brighter the light bulb will be.

How is energy transferred in a torch from the battery to the bulb - is it by electricity - is it by light - is it by sound - is it by thermal energy?
By electricity.By electricity.By electricity.By electricity.
Can aluminum foil make a light bulb work?
Yes. Aluminium is a very good conductor of electricity, and works with salt water.
Can a bulb light if electricity doesn't get to the bulb?
no
What does a battery use to produce electricity?
a battery has potential ( voltage). without a circuit atatched to it nothing happens. But when used in an electic ciruit, like with a light bulb, current will flow(amps). current flow is what causes your light bulb to light. A battery has the pressure (voltage) so to speak to cause current flow. Generally, current flows from negative to positive ina complete circuit.
What is the controlled variable for a light bulb and battery?
A light bulb and a battery simply being is not an experiment, so there is no variable at all.
What material will allow electricity to flow between a battery and light a light bulb?
A conductor - usually copper wire.
What material will allow electricity to flow between the battery and the light bulb?
Any conductor like copper or silver or aluminum
How does a battery powered light work?
The battery chemically stores electricity so when you 'switch on' the light then electricity flows from the battery to the bulb. The bulb the heats up to glow white and the reflector shines the light out of the battery powered light
How is electricity transferred from batteries to the light bulb?
Electricity is passed through a wire from battery to bulb
How do you build a conductivity tester?
Take two pieces of wire, one battery and one light bulb. Battery and light bulb should be the same voltage. Attach one end of one piece of wire to one pole of the battery (Soldering it would be best). Attach one end of the other piece of wire to the other pole of the battery and the other end of the wire to side conductor of the light bulb. You are done. To test the conductivity of something you simply touch the center conductor of the light bulb to one end of what you're testing and the other end of the first piece of wire to the other end of what you're testing. If what you're testing conducts electricity the current will run from the battery through what you're testing into the light bulb, out the other side of the light bulb and back to the battery and the light bulb will light up. If what you're testing doesn't conduct electricity, the electricity from the battery will not be able to pass through it to the light bulb and it won't light up. Good luck!
How can it be determined if an element will conduct electricity or not?
If you want to physically do it, connect up a simple circuit with wires, a battery and a small bulb. Put the object in the circuit (touching the wires) - if the bulb light, its a conductor.
To light up a light bulb we need to connect to a?
To light a light bulb you need to connect to a source of electricity like a battery or an electrical outlet.
Can potatoes power a light bulb?
Yes, accually potatoes are a very good conductor of electricity.
What describes electricity flowing from a battery through a switch to a light bulb?
A circuit
What provides the electricity to light up the bulb?
a battery or a power box by your house.
Is lampblack good conductor of electricity?
Yes, it is a good conductor of electricity.
