first of all, you need a bulb, a wire, and ONE light bulb. You clip the wire on the battery and touch the wire on the bottom of the light bulb
When connecting a volt meter to a light bulb to measure the voltage of the light bulb, run a third wire from where the wire enters the bulb to one terminal of the voltmeter and a fourth wire from the other side of the bulb to the other terminal of the voltmeter.
if the copper wire (s) were conneting the battery to the lamp removing one of the wires would break a circut and the lamp goes out.
If the tiny wire in a light bulb breaks, the circuit will be interrupted and the light bulb will stop working. The wire, called a filament, is responsible for producing light when electricity passes through it. Without the filament intact, the bulb cannot generate light.
In an incandescent light bulb the wire that gives off the light is called the Filament.
filament
the Sparks on the copper makes the wire on the light bulb makes the 9v light bulb turn on.
Make a circuit with 2 wires a batery and a light bulb and touch wire to medle on light bulb
You have to connect one conductor from potato to one terminal on light bulb and the other to the second conductor. Your light bulb must be a low voltage and low current bulb because a potato delivers very little power. Light bulbs that screw in would have one connection point on the screw in part and one at the bottom of the base of the bulb. It would be best to put the bulb in a socket that would allow easier connection of wires instead of trying to wrap the wire around the bulb.
When connecting a volt meter to a light bulb to measure the voltage of the light bulb, run a third wire from where the wire enters the bulb to one terminal of the voltmeter and a fourth wire from the other side of the bulb to the other terminal of the voltmeter.
People initially thought the light bulb wouldn't work because they believed the wire filaments would burn out quickly, the vacuum inside the bulb would not be maintained, and that electricity would be too expensive to produce light.
As the name implies, support wires support the filament wire in the bulb, The filament, of course is the wire that glows white hot, giving out light
