A rectangular parallelopiped is measured as 1 cm×1 cm×100 cm. If its specific resistance is 3×10⁻⁷ Ω m, then the resistance between its two opposite rectangular faces will be ×10⁻⁷ Ω.

Question

Accepted Answer

3. The rectangular faces measure 1 cm×100 cm, so A=10⁻²×1=10⁻² m² and the separation is l=1 cm=10⁻² m. R=(ρ l)/A=(3×10⁻⁷×10⁻²)/(10⁻²). R=3×10⁻⁷ Ω.
