More charge can be stored on a metal if it is highly polished when its surface is rough​

Answer»

EXPLANATION:

SURFACE charge density is more at sharp edges due to which there is chance of leakage of CHARGES. ... But, if a metal is HIGHLY polished, it does not have any pointed tips which can cause the leakage of charge. Hence, we can KEEP more charge on a highly polished than when its surface is rough.
