(General Physics) the electrical property of a material that determines the resistance of a piece of given dimensions. It is equal toRA/l, whereRis the resistance,Athe cross-sectional area, andlthe length, and is the reciprocal of conductivity. It is measured in ohms. Symbol:ρFormer name:...
resistance is directly proportional to the length and temperature while it is inversely proportional to the cross-sectional area of the material. resistance is only proportional to the temperature of the conductor. it also depends on the nature of the material of the conductor. 3 symbol r ρ...
