When current flow is obstructed in an electrical circuit, it is said to be experiencing resistance. Resistance is measured in ohms. It is denoted by the Greek letter omega . Mathematically, Resistance , Where = resistivity, = cross-sectional area , = length of the conductor,The resistance of a conductor depends upon its resistivity, length, and cross-sectional area. It also depends upon other physical factors like temperature etc. Thus, the resistance of a conductor depends on resistivity, length, and cross-sectional area of the conductor.
