Photoresistor
A photoresistor (also known as a light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases in resistance as a result of increasing luminosity (light) on its sensitive surface, in other words, it exhibits photoconductivity.A photoresistor can be used in light-sensitive detector circuits and light-activated and dark-activated switching circuits acting …
The Light Dependent Resistor (LDR)
If the position of the fixed resistor and LDR are swapped around, the behaviour of the circuit changes. In the example, we used the Type 2 LDR (the larger one) and a 4.7kΩ resistor, and achieved a dark value of 4.7V and a light value of 55mV. This is the complete opposite of what was above and is one way of achieving hardware inversion.

6.4: Kirchhoff''s Rules and Resistor Circuits
Kirchhoff''s First Rule. Kirchhoff''s first rule (the junction rule) applies to the charge entering and leaving a junction (Figure (PageIndex{2})).As stated earlier, a junction, or node, is a connection of three or more wires. Current is the flow of charge, and charge is conserved; thus, whatever charge flows into the junction must flow out.
