what is crosssection area and resistance
Answers
its length – the longer the wire, the greater its resistance. its cross-sectional area A – the greater the area, the less its resistance. the resistivity of the material r – the greater the resistivity, the greater its resistance.

Explanation:
crossection area
The crosssectional area is the area of a two dimensional shape that is obtained when a three dimensional object such as cylinder is sliced perpendicular to some specified axis. for example the cross section area of cylinder when slicer parallel to its base is a circle .
resistance
resistance is an electrical quantity that measures how the device or material reduces the electric current flow through it
the resistance is measured in ohms .
