A uniform wire of
Formula used :
Resistance of a wire is given by
ρ→ resistivity of the material
l→ length of the wire
A → cross sectional area of the wire
l is proportional to R.
When a uniform wire of resistance 50Ω is cut into 5 equal parts then resistance of each part is
Now they are connected in parallel.
Equalent resistance is calculated as
A uniform wire of resistance 50 Ω is cut into 5 equal parts. If the parts are connected in parallel then equivalent resistance is Ω. So option A is correct.
