WebNov 17, 2024 · LDR is also referred to as a photoresistor, photocell, or photoconductor. It is a specific kind of resistor, and the amount of light that strikes its surface affects how much resistance it exhibits. ... Intrinsic Photo Resistors: These resistors are pure semiconductors made of germanium or silicon. WebPhotoresistor. A photoresistor is made with photoconductive materials. Once the light with appropriate frequency drops on the photoresistor, then the pairs of charge carriers are formed which enhances the resistor’s conductivity at the same time, the resistivity will be decreased. Therefore, the photoresistor is responsive to incident light. pinewood best western wilmslow

Intrinsic photoresistor: This type of photoresistor uses a photoconductive material that involves excitation of charge carriers from the valence bands to the conduction band. Page 8 of 23. Extrinsic photoresistor: This type of photoresistor WebJul 21, 2024 · A Light-Dependent Resistor (also called LDR or photoresistor or photocell or photo conductive cell) is a passive circuit element whose resistance changes with change in the intensity of light. The resistance of an LDR decreases with the increase in the intensity of incident light. Therefore, the light dependent resistor exhibits photoconductivity. WebA photoresistor is a type of resistor whose resistance decreases when the intensity of light increases. In other words, the flow of electric current through the photoresistor increases when the intensity of light increases.
