Which metal is used in wires?
Which metal is used in wires? Copper Which wire can carry a higher current? Answer. “In solid wire of same length resistance of that wire is higher than stranded wire”. Hence stranded wire carries more current than solid wire due to lower resistance. Thus due to extra surface area more surface current flows Therefore in […]
