A glass rod can be charged by holding in hand, while an iron rod can be charged only by attaching it to an insulator. Explain.
Dear Student ,
Metals have free electrons which allow the conduction of charge. Thus, they are good conductors of electricity. Hence, if you rub a metal rod there would be no accumulation of electric charge on its surface. Non-metals, however, lack free electrons and on friction accumulate charges on their surfaces.
