The same voltages are applied to the ends of copper and aluminum conductors that have the same dimensions. Compare the amperage in them.
The current strength in a copper conductor is greater than in an aluminum one, because the current is inversely proportional to the resistance of the conductor at constant voltage, and aluminum has a higher resistivity than copper, therefore, the aluminum conductor has more resistance.
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.
