Question

Calculate the resistance of 2 m long copper wire of radius 1 mm. Resistivity of copper is 1.72 x 10-8 ohm-m.
Someone pls answer fast

Answer 1

Answer:

Given Resistivity of copper is 1.72 xx 10^-8 Omega m.

If R is the resistance of the given wire, then R=ρlA=(1.72×10-8Ωm)×(1000m)3. 14×10-6m2=5.48Ω.
