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. 

All of the factors that contribute to global winds are 

1) Uneven warming of the earth by the sun
2) Coriolis Effect
3) Convection Cells

Genes are units of heredity.

Strength of concrete increases with increase in water cement ratio as the strength of the cement is directly proportional to water cement ratio.
