WebA light-dependent resistor (LDR) is a special type of resistor whose resistance changes with the light level. As the light gets brighter, its resistance decreases. It can therefore be used as a simple light sensor. Examples of products include solar garden lights and street lighting. A thermistor works in a similar way except it responds to ... Webresistor: A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. Resistors can also be used to provide a specific voltage for …

WebDec 21, 2024 · Consider two resistors in a series circuit with a battery. As you might expect the total resistance in this circuit is higher than the resistance of each resistor, because the battery has to "push" the charge through both resistors one after the other. So the total potential difference of the supply is "shared" between the two resistors. WebThe Light-Dependent Resistor (LDR) A light-dependent resistor (LDR) is a non-ohmic conductor and sensory resistor. Its resistance automatically changes depending on the …
