(II) A rectangular solid made of carbon has sides of lengths 1.0 cm, 2.0 cm, and 4.0 cm, lying along the x, y, and z axes, respectively (Fig. 18–35). Determine the resistance for current that passes through the solid in (a) the x direction, (b) the y direction, and (c) the z direction. Assume the resistivity is ? = 3.0 × 10?5 ?·m.

Step 1
We know that the resistance of a material can be calculated using the formula: $R = \frac{\rho L}{A}$ where $R$ is the resistance, $\rho$ is the resistivity, $L$ is the length, and $A$ is the cross-sectional area. Show more…

(II) A rectangular solid made of carbon has sides of lengths $1.0 \mathrm{cm}, 2.0 \mathrm{cm},$ and $4.0 \mathrm{cm},$ lying along the $x, y,$ and $z$ axes, respectively (Fig. $35 ) .$ Determine the resistance for current that passes through the solid in $(a)$ the $x$ direction, $(b)$ the $y$ direction, and $(c)$ the $z$ direction. Assume the resistivity is $\rho=3.0 \times 10^{-5} \Omega \cdot \mathrm{m}$
A rectangular solid made of carbon has sides of lengths 1.0 cm, 2.0 cm, and 4.0 cm, lying along the x, y, and z axes, respectively (see Figure 1). Assume the resistivity is ρ = 2.9×10^-5 Ω·m. Determine the resistance for current that passes through the solid.
