The current flow through a conductor requires a source of electrical current, something to transport the current, and something that causes current to flow through a conductor. It is not required something that has air molecules [D].
Further explanation
When an electrical current flow into a conductor, the electrons are drifting into the metal. Electricity readily flows through a conductor as electrons move freely in the object. Electrical currents are produced when electrons are moving through a conductor. When it’s attached to the power supply, like a battery, a current will flow through any conductor, but the quantity of current that flows across it depends on the conductor’s strength. The higher its strength, the less it will pass over.
The electrical conductor is electrical materials, while insulators are not. Under normal temperatures and pressure, the finest electric conductor is the silver metal element such as:
• Aluminum
• Steel
• Mercury
• Iron
• Concrete
