Question

Why does a metal wire when connected to a cell offer resistance to the flow of current

Open in App

Solution

An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. ... The resistance of a thinwire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current
