Ohms law is the most fundamental law that governs the relationship between Voltage (V), Current (I), and Resistance(R). It was define by the German scientist Georg Simon Ohm, and hence is named after ...

The resistance of an NTC thermistor decreases with increasing temperature. A voltage-current graph for a thermistor is shown below. Voltage - Current graph for a thermistor as current and ...

Record voltage, current and diameter of the wire, d (supplied by the manufacture). Calculate resistance and cross section area, A, in mm 2 (A = \(\frac {{\pi }d^2}{4}\)). Plot a graph of ...
