Respuesta :
Yes without an eletrical current attached there would be no electrons.
The wires are empty of charge when there is no current flowing and no electrons moving through wire.
What is charge?
The charge is the physical quantity which defines the object's electric field. The charged objects creates the electric field around it and attracts or repels another objects coming into that field.
The like charges repels each other and unlike charges attract each other.
When a wire is connected with battery or voltage source and switch is on, the electrons leave from positive terminal and heading towards the negative terminal. Thereby, resulting in flow of current through wire.
Charge q = no of electrons x charge on electrons
Thus, Yes, wires are ever empty of charge.
