Silver is a better conductor of electricity than copper. Whey do we use copper wire for conduction of electricity ? |
| Answer» Solution :The resistivity of silver is `1.59xx10^(-8)Omegam" and that of COPPER is "1.68xx10^(-8)Omegam.` The resistivity of silver is LESS than copper. Hence, the conductivity of silver is more than copper. If we use silver for CONDUCTION of electricity it will be better, but silver is a costly metal than copper. Hence copper is widely USED for conduction. | |
