| Tell us about electrical resistance. What is the SI unit of resistance? What physical quantities does the resistance of the conductor depend on? What is the nature of this dependence?
The proportionality coefficient R in Ohm’s law is called electrical resistance. The SI unit of resistance is ai (ohm). The resistance depends on the resistivity of the conductor (inverse relationship), the length of the conductor and the cross-sectional area of the conductors (direct relationship).
