Question :

A thick and thin wire made ftom same material and of same length are connected one by one to same source. in which case a large current will flow in circuit? justify your answer?Submitted on 2/2/2024 | Answered by Vandana Rana

Answer :

The current will flow more easily through a thick wire than through a thin wire of the same material when connected to the same source. This is due to the fact that the resistance of a wire is inversly proportional to the square of its diameter. A thick wire has a greater diameter and hence lesser resistance making the current to flow through it more easily.

On the other hand, a thin wire has smaller diameter and hence greater resistance to the flow of current through it.
