Question

The resistance of a conducting wire X of length 1 m is 5 ohm. Calculate the
resistance of the wire made by the same material whose length is 4 times
and area of cross-section is 5 times that of wire X. (At same temperature ).​

Explanation:

Answer 2

Answer:

4 ohm

Explanation:

Resistivity of material = 5 ohm meter

since R = resistivity× length/ area

= 5×4/5

= 4 ohm
