I apologise if this is a very basic question but I hope you can help.
If I connect a wire to the positive terminal of my battery only, why do the electrons in the wire not flow out of the wire?
If the positive terminal consists of positive ions surely there is a lot of positive charge within this terminal attracting the electrons in the wire. The charge in the wire will be initially be equal due to the equal sum of protons and electrons. With there being an equal attractive and repulsive charge behind the electrons and a large attractive charge to the positive terminal why does this not result in a flow towards the positive terminal?
Why will the electrons not flow into the positive terminal until the positive charge in the wire due to electrons that have left equals the positive ions remaining in the positive terminal.
