how can you light a light bulb with one wire, a battery and bulb
Answers
Answer:
You don't need electrical wires to power a light bulb. You can use a battery! Just like a flashlight runs on batteries, you can connect a battery to a small light fixture or bulb to light it up. Follow the instructions below to learn how to make a battery-powered light bulb.
Materials:
Size D battery
Two pieces of insulated wire
A light bulb or very small light fixture
Tape (electrical tape is preferred, but any tape will work)
What you need to do:
Strip between ½ an inch and 1 inch (1.5 to 2.5 centimeters) of insulation off each end of each piece of wire [source: Dave].
Tape one end of one wire to the bottom, or negative, terminal of the battery. Tape the other end of the wire to the side of the light bulb stem [source: Energy Kids].
Tape one end of the other wire to the top, or positive, terminal of the battery. Tape the other end of the wire to the bottom of the light bulb stem. When you connect the two wires to the light bulb, it will light up [source: Dave]. Electrons flow out of the negative terminal of the battery, through the bulb and back into the positive side of the battery to make the bulb light up [source: Energy Kids].
Be careful when handling the exposed wires. Although it's minimal, there's an electric charge running through the wires [source: Electropaedia].
Answer:
i will connect battery's positive terminal to negetive terimal of the bulb and vice-versa through wire.Though the current will flow through the circiut and makes the bulb glow.
