We see always in source meter machines a LED which indicates the limit current. I want to know what is the limit current and what is the relationship between this later and the resistivity.

A source meter machine is a specialized electronic instrument used to measure and control voltage, current, and resistance in electrical circuits. It combines the functions of a power supply and a multimeter, allowing for precise and accurate measurements of these parameters.
Limit current, also known as compliance current, is the maximum amount of current that a source meter machine can output. It is the upper limit of the current range that the machine is capable of producing.
The limit current of a source meter machine is determined by the maximum voltage and resistance values that the machine is designed to handle. These values are set by the manufacturer and may vary depending on the specific model of the machine.
Resistivity is a measure of a material's ability to resist the flow of electric current. It is measured in ohms per meter (Ω/m) and is dependent on the material's composition and temperature. In a source meter machine, resistivity is typically measured by applying a known voltage and measuring the resulting current, then using Ohm's law (V=IR) to calculate the resistivity.
Source meter machines are commonly used in scientific research to precisely control and measure electrical parameters in experiments. They are often used in materials science, nanotechnology, and electronics research to study the properties of various materials and devices, as well as in testing and characterization of electrical components.
