How to use voltage divider
WebA voltage divider does exactly as its name suggests - it divides a supply voltage across two resistors which are connected in series. The two resistors may have fixed values or … WebConnect the pins of your photoresistor to the electrodes of the multimeter. Set the multiumeter to measure resistance (ohm-meter). This will allow you to measure the impedance (resistance) of a photoresistor. Take a few measurements, under different light conditions. You will see that the impedance varies, but is always very high.
