WebJul 18, 2015 · As long as you measure the resistance between opposite sides of a square, you will get the same answer regardless of the size of that square. Well made and clean PC boards can have surface resistivity in the 10s of GΩ per square. WebMar 5, 2024 · However, in many practical applications the temperature coefficient is defined in relation to the change in resistance compared with the resistivity at a temperature of 20 o C, and is given by the equation.
