Will current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why?
ScienceClass 10CBSEAnswered 27 Mar 2026
Answer
Solution:
Resistance is given by the equation,
R = ρ l/A
where,
ρ is the resistivity of the material of the wire,
l is the length of the wire
A is the area of the cross-section of the wire.
From the equation, it is evident that the area of the cross-section of wire is inversely proportional to the resistance. Therefore, the thinner the wire, the more the resistance and vice versa. Hence, current flows more easily through a thick wire than a thin wire.
