Using the electronic theory of metals, guess how the resistance of a metal conductor depends on its cross section.

Of two conductors with different cross-sectional areas, the larger conductor must have the lower resistance. Indeed, in this case, more conduction electrons will pass through the cross section of a larger area in the same time.
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.
