Question

why does a metal wire when connected to cell ofer resistance to the flow of current - give reason
​

Answer 1

Answer:

due to continuous collisions with kernel electrons speed decreases in wire

Explanation:

kernel is the remaining part of atom

Answer 2

Answer:

A metal wire has free electrons which move in random directions. When the ends of the wire are connected to a cell, the electrons start moving from the negative terminal of the cell to its positive terminal through the metal wire. ... Thus, the wire offers resistance to the flow of current (or electrons) through it.
