Rate OF conduction (non-uniform area)

Assertion : If a current is flowing through a conducting wire of non-uniform cross-section, drift speed and resistance both will increase at a section where cross-sectional area is less. Reason : Current density at such sections is more where cross-sectional area is less.

Composite function(uniform & non-uniform)

When the rate of flow of charge through a metallic condoctor of non-uniform cross-section is uniform, then the quantity that remains constant along the conductor is
