The obstruction of the conductor to the current is called the resistance of the conductor, and the resistance is also a physical quantity that describes the conductivity of the conductor.


Factors that affect resistance


  • Length of material

  • The cross-sectional area of the material

  • Properties of materials

  • Environment temperature


The basic formula of resistance


  • The relationship between resistance, voltage and current (Ohm's Law)

  • The relationship between resistance, power and voltage

  • The relationship between resistance, power and current
