Question

8. Two wires of same metal have the same length but their cross-sectional areas are in the
natio 3:1. The resistance of the thicker wire is 100. What will be the resistance of the
other wire?​

Answer 1

Answer:

hope this helps...

Explanation:

Ratio of cross-sectional areas of the wires = 3 : 1 and resistance of thick wire (R1) = 10 Ω.

and equivalent resistance of these two resistances in series combination = R1 + R2 = 30+ 10 = 40 Ω.
