What is an Ohm-Mile? Definition, Uses, and Examples

Ohm-mile is a unit of measurement that combines the units of electrical resistance (ohms) and distance (miles). It is used to express the resistance of an electrical conductor over a specific distance.

One ohm-mile is defined as the resistance of a conductor that spans one mile (1.60934 kilometers) and has a resistance of one ohm at its ends. This means that if you have a conductor with a resistance of one ohm over a distance of one mile, it would have an overall resistance of one ohm-mile.

Ohm-mile is used in the electrical engineering industry to describe the performance of long transmission lines or cables. It is a useful unit of measurement because it allows engineers to easily calculate the total resistance of a line or cable, which is important for determining its voltage drop and power loss.
