Homework Equations
Capacitance = k(epsilon zero) (Area) / (distance)
Length (thickness) = (Volt)(Area) / (Current * Resistivity)
The Attempt at a Solution
Given:
Capacitance : 480 * 10 ^ -12 Farad
Radius: 24 * 10 ^ - 2 m
Area: pi * r ^ 2
dielectric constant of polystyrene: 2.6
breakdown field(MV/m) : 25
Resistivity of Polystyrene : 10 ^ 15
distance = (2.6)(8.85 * 10 ^ -12) (3.14 * (24* 10 ^ -2) ^ 2) / (480 * 10 ^ -12)
however finding the distance does not seem to help me at all since the other equation do not involve distance
any guidance would help
