Ohm's Law
Define:- Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship
Joule's laws
Define:- Joule's laws are two laws about heat produced by an electric current and the energy dependence of a gas to pressure, volume and temperature.
Joule's first law shows the relation between heat generated by an electric current flowing through a conductor. It is named after James Prescott Joule and shown as:
