combination.​

Answer 1

Answer:

The resistance of an object (i.e., a resistor ) depends on its shape and the material of which it is composed. Resistivity ρ is an intrinsic property of a material and directly proportional to the total resistance R, an extrinsic quantity that depends on the length and cross-sectional area of a resistor.

I hope you know the formula ...
