Ohm's law
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:
where I is the electric current, the electric conductivity G, U is the voltage and R is the electrical resistance.
where I is the electric current, the electric conductivity G, U is the voltage and R is the electrical resistance.
