Three wires of the same cross-sectional area and length – copper, tungsten and lead – are connected in parallel in the circuit.

Three wires of the same cross-sectional area and length – copper, tungsten and lead – are connected in parallel in the circuit. Which one has the highest amperage?

Large current on a copper conductor because the stranded has a lower resistivity, and the current strength is inversely proportional to the resistance at the same voltage.

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.
