Resistance logger sensor NUL-249

Resistance logger sensor


The sensor measures the current through the resistance and the voltage on it, its output is a resistance value. Using ohm’s law (R = V/I) the resistance is calculated from the current and voltage values. Possible experiments that can be performed are: Electrical components resistance measurements, electrical parallel circuits, electrical series circuits and electronics.
