Electrical resistance of the conductor, specific resistance
2
The physical quantity that characterizes the ability of a conductor to resist current is called the electrical resistance. It is denoted by the letter R.
3
The formula for determining the resistance of a conductor
The physical quantity that indicates the resistance of a given conductor to the current flowing through it is called the resistance of the conductor. R=ρl/A
The resistance of the conductor is directly proportional to the length l
The cross-sectional area A of the resistance of the conductor is inversely proportional
The resistivity of the conductor ρ is directly proportional
4
The value that characterizes the material of the conductor is called the resistivity. We denote it by ρ.
Measuring instrument "Ohmmeter".The unit of resistance in the SI system
