Electric Charge

A fundamental property of matter that allows it to interact through electrical forces. It can be positive (+) or negative (-) and is measured in Coulombs.

Superposition Principle

The principle stating that the total electric force on a charged particle is the vector sum of all individual forces exerted by other charged particles in the system.

Quantization of Charge

The idea that electric charge exists only in discrete units, which are multiples of the fundamental charge, 'e' (the charge of a single proton or electron).

What are the types of electric charge?

Positive or negative.

Study Notes

Electric Charge

Charge is a property of a substance.
It allows substances to exert electric forces or respond to electric fields.
The unit of charge is Coulomb (C).
Charge can be positive or negative.

Quantization of Charge

A charge is always a whole number multiple of the elementary charge.
Charge cannot be a decimal.
Possible charges are (+1e, +2e, +3e...).
Impossible charges are (+0.5e, +1/3e, +5/7e...).

Superposition Principle

The net force on a charged particle due to other charges is equal to the vector sum of the forces exerted by each individual charge.
This principle is used to calculate the net force on a particle within a system of charged particles.
