# Current Electricity

In electrostatics, we study electrostatic interactions where electric charges are at rest in our frame of reference. Now think about what happens when we are at rest in our frame of reference and the charge under consideration is moving with velocity v with respect to us such a moving charge leads to the origin of magnetism which we will discuss in a later section.

### What is electricity?

Electricity deals with stationary and moving electric charges, the actions of force between these charges, and the electric and magnetic fields generated by them. Electrostatics is simply electricity at rest. Electricity is the backbone of modern society in which we use various instruments which depend on electric current for their functioning and without it, we would not have telephones, television, household appliances and many more gadgets which are now part of our daily life. In electricity, we study the motion of electric charges, or electric currents, and also the voltages that produce currents and the ways to control currents.

## What is required for an electric charge to flow through a wire?

An electrical current is the movement of charged particles, such as electrons and ions, through an electrical conductor. In a conductor electric charges do not start to move on their own. They move inside a conductor only if they are forced to move in a particular direction. This happens when a potential difference is created …
