Question

What is the formula for the capacitance of a cylindrical capacitor?
Options
A C = 2πε₀l / ln(R_a/R_b)
Correct Answer
B C = ε₀A/d
C C = 4πε₀R
D C = ε₀l / ln(R_a/R_b)
Correct Answer

Option A is the correct answer.

Detailed Explanation

For a cylindrical capacitor, C = 2πε₀l / ln(R_a/R_b), where l is length, R_a is outer radius, R_b is inner radius.

Hint

Logarithmic dependence on radii.
