The surface resistivity of a material is the ratio of the potential gradient parallel to the current along its surface to the current per unit width of the surface, usually expressed in ohms. Surface resistivity of a material is numerically equal to the surface resistance between two electrodes forming opposite sides of a square, the square size being immaterial.
The resistance of a material to the flow of electric current over its surface. Measured in ohms/centimeter.
Surface resistivity is a numerical measure of material or surface's ability to resist the flow of electrical current. It is expressed in ohms per square because surface resistivity is numerically equal to the resistance between two electrodes forming opposite sides of a square. The size of the square is immaterial.

Expressed in ohms/square. It is numerically equal to the resistance between two electrodes forming opposite sides of a square on the surface of a material. The size of the square is irrelevant. For conductive materials, surface resistivity is the ratio of the volume resistivity to the fabric thickness (r/t).
The resistance of a material between two opposite sides of a unit square of its surface, commonly expressed in ohms per square.
The resistance of a material between two opposite sides of a unit square of its surface. It is usually expressed in ohms.
For electric current flowing across a surface, the ratio of DC voltage drop per unit length to the surface current per unit width. In effect, the surface resistivity is the resistance between two opposite sides of a square and is independent of the size of the square or its dimensional units. Surface resistivity is expressed in ohms/square. When using a concentric ring fixture, resistivity is calculated by using the following expression, where D1 = outside diameter of inner electrode, D2 = Inside diameter of outer electrode, and R = measured resistance in ohms
The electrical resistance of a material between the two opposite points of a unit of its surface.
the measure of a surface's resistance to the flow of electricity, usually expressed in ohms/square.
The resistance to a current flow along the surface of an insulator material. Measure in ohms-cm.
The electrical resistance between opposite edges of a unit square of insulating material. It is commonly expressed in ohms. (Also covered in ASTM D257-54T).
