What is ohm's law ?

Thursday 19th January 2017 science law ohms theory principle

Ohm's law is the mathematical relationship between electric current,voltage and resistance.Ohm's law states that-The potential difference across any ideal conductor is proportional to the current through it.

According to ohm's law, V=IR

                                                where R is the proportionality constant and called resistance

                                                            V is the potential difference between two points including resistance.

                                                             I is the current flowing the resistance
