Measurement of Low value resistance (0.1 to 50 Ohm)

The previous voltage divider design is suitable for only measurement of higher values of resistance (50 Ohm to 1 MOhm) to measure very small value resistance we have built this circuit, it consists of constant current source of 100mAmp. Measuring voltage drop across a resistor having constant current gives us resistance value (R = V / I).
V = I x R
R = V / I Continue reading Measurement of Low value resistance (0.1 to 50 Ohm)

Arduino Resistance Measurement


The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor. It is measured in Ohms.
