Video: Determining the Current through a Cylinder of Known Resistivity
A rod of silicon is used in a particle detector. The rod is 18.0 cm long and has a diameter of 3.00 cm. Find the current through the rod when a potential difference of 1.30 × 10³ V is applied across its length. Use a value of 2300 Ω ⋅ m for the resistivity of pure silicon.
