[ \boxed{180 \ \Omega} ] If you have a specific NCERT chapter, class, and subject (e.g., Class 10 Science Ch 12 Electricity, or Class 12 Physics Ch 1 Electric Charges), I can create a complete, accurate, and original set of solutions for all the exercises. Just tell me the details.

We know the formula for resistance:

[ A \times L = A' \times L' ] [ A \times L = A' \times (3L) ] [ A' = \frac{A}{3} ] ncert solutions

New resistance: [ R' = \rho \frac{L'}{A'} = \rho \frac{3L}{A/3} ] [ R' = \rho \frac{3L \times 3}{A} = \rho \frac{9L}{A} ] [ R' = 9 \left( \rho \frac{L}{A} \right) ] [ R' = 9 \times R ] [ \boxed{180 \ \Omega} ] If you have
