SUMMARY
The discussion focuses on solving an Ohm's Law problem involving resistance (R) and voltage (V) calculations. The user attempted to calculate resistance using the formula R = (Rou*A)/L, where Rou is the resistivity, A is the cross-sectional area, and L is the length. The user reported a calculated resistance of 1.5873882E-11 Ohms and voltage of 4.81026727E-13 V, but was informed that their resistance calculation was incorrect and advised to check their formula.
