Answer 1

Ello user !!!!!!

Here is your answer,

=============================================

Resistant is offering resistance to something .

Resistivity is a measure of the resisting power of a specified material to the flow of an electric current.

Answer 2

Resistance is the property of a material by virtue of which it opposes the flow of current through it

It is equal to the ratio of the potential difference applied across its ends and the current flowing through it.

SI unit is ohm

Factors affecting resistance:

1. Length of conductor

2. Area of cross-section of conductor

3. Nature of material of the conductor

4. Temperature of the conductor

Resistivity or specific resistance is the amount of resistance offered by a conductor of unit length and unit area of cross-section.

It is the constant (rho)

SI unit is ohm meter

Factors affecting resistivity

1. Materials

2. Temperature
