Charge (q) is a physical property of matter that causes it to experience a force when placed in an electromagnetic field. Note charge is just a property, however, particles possessing this property, like, ______ are also some times termed as charge, this is technically incorrect as charge is not matter, and it is just a property.

Electric Field (E) is a measure of the strength of ______ per unit charge at a given point. A unidirectional electric field gets established when we put a cell in an electrical circuit. It is the electric field that results in a flow of electric current in the circuit. Larger the Electric field, higher is the rate of flow of charge (current).

As you know metals are rich in ______, which are constantly in motion within the conductor. Why do metals have a large number of ______. From where do these ______ come from. The presence or otherwise, of ______ depends upon the nature of the materials. Metals have a tendency to lose their outer shell electrons easily. Their atoms, which contribute to ______, become ions. The word „current‟ means „flow‟ hence electric current means „flow of charge‟.

Study Notes
Electric Charge and Electric Field
- Charge is a physical property of matter that causes it to experience a force when placed in an electromagnetic field.
- Charge is not matter, but rather a property of matter.
- Particles possessing charge, such as electrons, are sometimes termed as charge, but this is technically incorrect.
Potential Difference (V)
- Potential difference (V) equals the work done in carrying a unit charge from one point to another.
- It is also defined as work done per unit charge.
Electric Field (E)
- Electric Field (E) is a measure of the strength of force per unit charge at a given point.
- A unidirectional electric field is established when a cell is placed in an electrical circuit.
- The electric field results in a flow of electric current in the circuit, and a larger electric field leads to a higher rate of flow of charge (current).
Metals and Free Electrons
- Metals have a large number of free electrons due to their tendency to lose their outer shell electrons easily.
- These free electrons come from the atoms of the metal, which contribute to the flow of charge.
- The presence or otherwise of free electrons depends on the nature of the materials.
Electric Current
- The word "current" means "flow", hence electric current means "flow of charge".
