difference between restance and resistivity
Answers
Explanation:
One of the major difference between the resistance and the resistivity of the material is that the resistance opposes the flow of free electrons whereas the resistivity is the property of the material which defines the resistance of the material having specific dimension.
resistance:-
The resistance can be defined as the material’s property which makes an obstruction within the current flow. As the voltage supply is given across the conductor, then the electrons flow will be there within an exact direction. So the heat can be generated while electrons flow collapses with molecules or atoms. These will oppose the flow of electrons within a material. This is named as the resistance and it is denoted with the following formula.
R = ρ x l / a
resistivity:-
The precise resistance is known as resistivity. It signifies the resistance of the object which has precise dimensions like the material which has one-meter length as well as one square meter region of a cross-section.
The material’s resistivity formula is given below.
ρ = R x a / l
