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.
It light up. ;)
i will tell you how if you tell me what this project is called,it uses light bulb, copper wires,holder,6 volt battery.
An item of fruit, a copper penny, a nail and wire. Connect all this up to a bulb and you have a lamp.
If you connect the circuit properly the bulb should light up. That means attaching the left side of the battery to the right side of the bulb using a wire and attaching the right side of the battery to the left side of the bulb. If you do that the your bulb should turn on. If it doesn't then try changing the battery or the bulb.
If the voltage is appropriate, the bulb will shine.
Get your bulb, it should be a very small wattage (weak) one, get your battery and wires, connect one wire to plus side of abttery and other wire to minus side of battery, then connect to the bulb, you may have to play around a bit to find a connection that produces light.
Simply connect the -ve of the bulb to -ve of the battery and +ve of bulb to +ve of battery using an electrically conductive wire, the bulb will light automatically.
The battery life (assuming it is a primary cell) is determined by the Ampere-hour drawn from it. You cannot connect a 3.5V bulb directly to a 9V battery. The bulb will fuse.
To light a light bulb you need to connect to a source of electricity like a battery or an electrical outlet.
connect the light bulb to the positive wire like a inline fuse and then connect the wire to the battery it should just burn out the bulb
Center terminal is connected to the positive from the battery. Outside is connected to ground (-).
