Dr. BR Ambedkar was elected to Constituent Assembly from West Bengal.

Resistivity :

Resistivity is a measure of the resistance to the flow of electrons. 

Conductivity :

Conductivity is just the inverse of resistivity, σ = 1/ρ, where σ is conductivity and ρ is resistivity.

Example:

Think of a pipe and water, the bigger the pipe, the easier water can flow and thus the lower the resistance. 

Self pollination occurs in the flowers when the pollen grains of the flower falls on the stigma of the same due to wind or insects like moths and bees. This lead to the inbreeding.

Shillong is the capital city of Meghalaya state in India. It is well known tourist place as a hill station in northeast India which attracts tourists all over the world.

The resistivity of wire or the metal conductor is depend on the number density of free electrons in the conductor. so its mainly depends on nature of the material
