What does insulated wire do?How does it differ from regular wire used on breadboards?
Insulated wire is .... insulated. That is, it has a layer of plastic or rubber around it so that there is no exposed metal (except at the ends) and thus minimizes the shock hazard, and also helps prevent accidental shorts between wires. Non insulated wire is bare, it has no insulation, it's just a thin copper bar. You can use either on breadboards, so I don't know what you mean by regular wire. .
