A coaxial resistor of length L consists of two concentric cylinders. The inner cylinder
has radius rand is made of material with conductivity o₁, and the outer cylinder, extending
between rand ⁄2, is made of a material with conductivity ₂. If the to ends of the resistor are
capped with conducting plates.
a) Solve for the resistance between the two ends symbolically
b) Solve for the resistance of a hollow carbon cylinder 10 cm long with r₁=2 cm and r₂=3 cm.
