Question

What is difference between ohms meter square and ohms meter?

Answer 1

Answer:

An Ohm•m is defined as a resistance of a conductor, which is 1 m long, has a cross-sectional area of 1 m² and resistance of 1 Ohm. To make calculations simpler, it is common in electrical engineering to use the derivative of the value of resistivity, which is measured in Ohm•mm²/m.
