Resistance And Resistivity

Specific Resistance or Resistivity

The lengths,resistances and resistivities of materials of two wires-each is in the ratio of 1:2 What is the ratio between their diameters?

What are the factors on which resistance of a conductor depend? Hence define specific resistance (or resistivity)?

What is the relation between resistance (R),"resistivity"(rho), length(l) and area of cross section (A) of a conductor ?

Define the terms resistance , resistivity , conductance and specific conductance. Write their units.

Write down the units of resistance, resistivity, conductance and conductivity?

Define specific resistance (resistivity). State its unit and dimension.
