The Electrical properties of a given material are determined by the potential difference (V)or the flow of current (I). The ohm’s law establishes a relationship between these two quantities.

It states that

For a given material, the greater the voltage, the more the current i.e. the current

is proportional to the applied voltage.

ohm law says that the voltage on two heads of a resistant carrying (I) ampere current with value of resistant equal to (R) ohms is equal to (I*R) volts. in other word if you apply (V) volts on a (R) ohm resistant and measure the current passing through it the current will be equal to V/R amperes. if we apply a (V) volts voltage on an unknown resistant and and measure the current passing through it equal to (I) amperes we can find value of resistant by R=V/I note that this law says that we can not apply 1 volt on a 1 ohm resistant and force it to carry a current not equals to 1 amperes. (the force for passing current through a resistant is voltage itself so for increasing the current passing a resistant U should decrease the resistance or increase the voltage and no other way is possible) this law in mathematics form is V=R*I were V is the voltage on two heads of resistant, I is current passing through resistant and R is the value of resistance.
