Resistivity
Resitance variation with Length (l) and Area (A) of cross section has a constant called
RESISTIVITY
RESISTANCE IS PROPORTIONAL TO LENGTH and INVERSELY RELATED TO AREA OF CROSS SECTION
Units of Resistivity: ?
Conductivity is inverse of resistivity. (Copper, Silver excellent conductors)
Resistivity INCREASES WITH TEMPERATURE
