Final answer:
Electricity involves the movement of electrons along a conductor, with electric current represented by the flow of these electrons, typically from a low-potential point to a high-potential one in a circuit.
Step-by-step explanation:
Electricity is the movement of electrons from one atom to another along a conductor. When we talk about electric current, we refer to it as the charges that move in a conductor. This movement of charge is typically in the direction that negative charge would flow, even though conventional current is taken to be in the direction that positive charge would flow, a concept dating back to Benjamin Franklin in the 1700s.
Specifically, in metal wires like copper, current is carried by electrons, which makes them excellent conductors. These electrons, also known as conduction electrons, are loosely bound and can easily move from atom to atom. This facilitates the flow of electricity when a potential difference is present, such as when a battery's terminals are connected by a conducting wire.
