Answer / Vinod Kumar Arya

To find the resistance (R) of a single-core copper cable with a length of 50 meters, cross-sectional area (A) of 16 square millimeters, and specific resistance (ρ) of copper (0.01724 ohm-mm²/m), use the formula R = ρ * L / A.nCalculate the resistance: R = 0.01724 * 50 / 16 = 0.438 ohms.
