Introduction to chargesINTRODUCTION TO CHARGES
Electrostatics is the branch of physics concerned with static charges and the electrostatic field. Electrostatics is defined as theory dealing with electrical charges or static electricity.
There are two types of charges: positive and negative.
There exist in nature two types of charges: positive and negative. The force between them is such that like
charges repel and opposite charges attract. Properties of electric charges:


Like charges repel each other and opposite charges attract each other.
Total charge of the universe is a constant.
All charges in nature are certain integral multiples of a basic unit charge. This is called quantisation of electric charge.
Electric charges are additive.



Electric charge is a scalar quantity.
