What will be the resistance of an aluminium wire of length 1.2 m and cross sectional area $2.6 mm^2$. The resistivity of aluminium is $2.6 \times 10^{-8} \Omega m$ |
$1.2 \times 10^{-8} \Omega$ $1.2 \times 10^{-5} \Omega$ $1.2 \times 10^{-2} \Omega$ $2.2 \times 10^{-2} \Omega$ |
$1.2 \times 10^{-2} \Omega$ |
The correct answer is Option (3) → $1.2 \times 10^{-2} \Omega$ |
