Vedclass · Answer

(B) Given: Resistivity $ho = 3 	imes 10^{-7} \, \Omega \cdot m$. Dimensions of the block are $1 \, cm 	imes 1 \, cm 	imes 100 \, cm$. For the resistance between the rectangular faces (the $1 \, cm 	imes 100 \, cm$ faces),the length $l$ of the current path is the remaining dimension,$l = 1 \, cm = 10^{-2} \, m$. The area of cross-section $A$ is $1 \, cm 	imes 100 \, cm = 100 \, cm^2 = 100 	imes 10^{-4} \, m^2 = 10^{-2} \, m^2$. The formula for resistance is $R = ho \frac{l}{A}$. Substituting the values: $R = (3 	imes 10^{-7} \, \Omega \cdot m) 	imes \frac{10^{-2} \, m}{10^{-2} \, m^2}$. $R = 3 	imes 10^{-7} \, \Omega$.

What is the resistance between the rectangular faces of a block with resistivity $3 \times 10^{-7} \, \Omega \cdot m$ and dimensions $1 \, cm \times 1 \, cm \times 100 \, cm$?
