Question

How does the presence of impurities in a metal affect its resistance?? a thumbs up for sure

Answer 1

The presence of impurities in a metal has an important effect on its resistance.

Impurities make the metal highly resistant.

So, the more impurities will be added to a metal, the more strong it will be.

So in brief it can be said that the relation between the metal and the impurities is directly proportional.

Answer 2

HEY!!

▶▶The presence of impurities in a metal increases its resistivity (also resistance) and it does not undergo oxidation easily even at a high temperature.
