RESISTANCE
1.Resistance denoted by R
2.Its units are ohms
3.Definition is
obstruction to flow of charge is called resistance
4.laws of resistance
resistance is directly proportional to length of conductor
R∝L
resistance is inversely proportinal to area of the conductor
Rα1/A
RαL/A
removing proportinality constant keep a constant rho(p)
R=pl/A
5.where rho p is called as resistivity or specific resistance
