COPPER
[tex]\large\mathcal{QUESTION:}[/tex]
- Why is copper not usually used in over head electric cable?
[tex]\large\mathcal{ANSWER:}[/tex]
- It is because copper has a high current density, which means it can carry more current per unit of cross-sectional area. Copper conductors have a smaller cross-sectional area as a result. Copper, on the other hand, is rarely used for overhead power lines due to its higher cost and scarcity.
