An electric current is a flow of particles (electrons) flowing through wires and components. It is the rate of flow of charge. If the electric charge flows through a conductor, we say that there is an electric current

An electrical circuit is a path or line through which an electrical current flows. The path may be closed (joined at both ends), making it a loop. A closed circuit makes electrical current flow possible. It may also be an open circuit where the electron flow is cut short because the path is broken. An open circuit does not allow electrical current to flow


The material with many free electrons allows easy transfer of electrical energy and is therefore called a conductor. If we send an energetic electron into a conductor, it will impact a free electron, knocking it down the line until it hits another free electron. This sets up a chain reaction of impacts that conducts the electrical energy through the material.


On the other end of the spectrum, there are atoms that hold on to their electrons very tightly. A material that contains these types of atoms has very few, if any, free electrons and does not transfer electrical energy well, if at all. This type of material is called an insulator.

# Electric Current --> The rate of flow of electric charge is known as electric current.
•Formula --> I=q/t...where I= electric current,q=charge,t=time.

# Electric circuit -->A continuous and closed path of an electric current is called an electric circuit.

# Conductor --> Through which heat / electricity can easily flow. ex=all metals.

# Insulator --> through which heat /electricity cannot flow. ex=cardboard,paper etc.
