1- COULOMB'S LAW:- It states that the magnitude of electrostatic force between two point charges is directly proportional to the product of magnitude of charge and inversely proportional to the square of the distance between them.

2- OHM'S LAW :- It states that the current passing through a conductor is directly proportional to the potential difference applied across the ends provided the temperature and other physical condition of the  conductor is kept constant
3- JOULES'S LAW :- When electric current passes through a conductor , the energy produced is proportional to the work done by the current.
Mathematically, W = I (square) Rt.
