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.
