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).
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
