The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current whichflows through it: If the resistance is constant over a considerable range of voltage, then Ohm's law, I = V/R, can be used to predict the behavior of the material

resistance are hindrance in path of current .
formula of resistance..
R= v/I where,
R = resistance,
v= potential difference,
I =current.
