De Broglie
Albert Einstein applied the concept of a quantum to explain the photoelectric effect in his 1905 paper. He proposed that light consists of discrete packets of energy called photons, which interact with electrons in materials to release them from the surface.
The relationship between the voltage applied to a circuit and the velocity of electrons within that circuit is direct. When a higher voltage is applied to a circuit, the electrons within the circuit move faster, resulting in an increase in their velocity.

When a voltage is applied to a conductor, free electrons gain energy and move in response to the electric field created by the voltage. This movement of electrons constitutes an electric current flowing through the conductor.
Current flows in conductors when a voltage is applied across them, creating an electric field that causes free electrons to move in the direction of the applied voltage. This movement of electrons constitutes an electric current. The current flow is facilitated by the presence of a closed circuit that allows the electrons to move continuously from the source of voltage to the load and back.

The model is applied to movement and position of electrons in the atom.

Electrons in Bohr's model of the atom
Isaac Newton has many contibutions in applied science and engineering.
When an electric field is applied to a metallic crystal, the movement of electrons is towards the direction opposite to the field. This is because electrons are negatively charged particles and will experience a force in the opposite direction to the electric field. This movement of electrons constitutes an electric current.
The term conductor is generally applied to a substance or material that has a lot of free electrons in it. The name conductor is applied because the free electrons are already there. A material does not have free electrons because it is a conductor, but is a conductor because it has a lot of free electrons. That said, let's look at what's going on. These free electrons have energies that permit them to "wander" through the conductor; they're not "locked into" the structure of the material. And when a voltage (potential difference) is applied, current flows through the conductor because the free electrons are moving. They're made to move by the applied voltage. If we take the case of a wire in a circuit, the wire is a conductor. This wire, say a copper one, has many free electrons in it, and when we apply a voltage, electrons move. The voltage forces electrons into one end of the wire, and the free electrons "shift over" and electrons emerge from the other end of the wire. This movement of free electrons in response to an applied voltage through an conductor is the essence of current flow in that conductor.

when no electricity flow then chare are in condition of static
