## How does AC current flow in a wire?

In AC, a changing magnetic field creates a changing electric field, and a changing electric field creates a changing magnetic field. When AC flows in a wire, a changing magnetic field is created in the wire. This induces its own current in the wire in the opposite direction to the original.

## How does AC power work in a house?

The electrical current in your house is AC. This comes from power plants that are operated by the electric company and is carried through power lines. The direction of current is switching back and forth 60 times each second (60 Hertz) in the United States. … The light bulb does not care if it is using DC or AC current.

## How does electricity flow through a wire?

Electric current (electricity) is a flow or movement of electrical charge. The electricity that is conducted through copper wires in your home consists of moving electrons. The protons and neutrons of the copper atoms do not move. … The wire is “full” of atoms and free electrons and the electrons move among the atoms.

## How does AC current move forward?

In alternating current, the electrons don’t move in only one direction. Instead, they hop from atom to atom in one direction for a while, and then turn around and hop from atom to atom in the opposite direction. … In alternating current, the electrons don’t move steadily forward. Instead, they just move back and forth.

## Why AC current is used in homes?

Because high voltages are more efficient for sending electricity over long distances, AC has an advantage over DC. This is because the high voltages from the power plant for home use can be easily reduced to a safer voltage. The voltage is changed with a transformer.

## What is the working principle of AC generator?

AC generators work on the principle of Faraday’s law of electromagnetic induction. This law states that electro motive force is generated in a current carrying loop that is placed in a uniform magnetic field.
