How do I connect a copper wire to a 9 volt battery using a 4 watt lightbulb?
I am doing a project and need to connect a copper wire to a 9 volt battery on one end and the other end to a 4 watt battery.I need help on how to properly connect the wires. Thank you. I really appreciate it. You can solder it on using a soldering iron but i doubt you can get one at home. Check at school.
