WebFeb 24, 2012 · A Light Dependent Resistor (also known as a photoresistor or LDR) is a device whose resistivity is a function of the incident electromagnetic radiation. Hence, … WebPhotoresistor. A photoresistor (also known as a photocell, or light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases resistance with respect to receiving luminosity (light) on the component's sensitive surface. The resistance of a photoresistor decreases with increase in incident light intensity; in other ...

WebPhotoresistors, also known as LDR (light-dependent resistors), are components made of semiconductors. A photoresistor is sensitive to light. Its resistance decreases when lighting increases ( Figure 1.15 ). Photoresistors have multiple uses, for example, automatic door opening. Sign in to download full-size image. WebI'm doing the experiment described here and I have a few questions about it.
