When the terminals of a cell are connected to the ends of an iron rod, electric current flows, whereas when the terminals are connected to the ends of a wooden rod, no current flows. Explain.

Text Solution

Verified by Experts

Iron is a good conductor whereas wood is an insulator. An electron in an insulator is held near the position of a particular atom/ molecule and is not allowed to pass from one molecular site to next Hence no electrons flow, thus no current flow.
