WebImage from Platt. A photoresistor—sometimes called a photocell or light-dependent resistor (LDR)—varies its resistance in response to light. They are small, inexpensive, and easy-to-use. Consequently, photoresistors are popular in children’s toys (see example below), nightlights, clock radios, and other inexpensive gadgets. WebThe symbol for a photoresistor. A photoresistor (also known as a photocell, or light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases …

This symbol shows arrows shining on it, representing the light rays. The hands resemble that of the photodiode or the phototransistor circuit. ... Both the LDR and the photocell work on principles. The LDR works on the principle of its resistance reducing with a rise in light ... blcn fact sheetWebIn the above circuit (Fig. A) R1 is a CdS photocell in series with a 1000-ohm resistor. The 5 volts form VCC divides across R1 and R2 in proportion to their resistance. For example, if R1 = R2, one would read 2.5 volts across each component. Using a DC voltmeter (black lead on ground, red lead at V) one will read 2.5 volts. franklin county assessors pasco waWebA photo-resistor changes its resistance based on the amount of light that hits it. When a lot of light hits it, it has almost zero resistance -- it conducts electricity very well. When no light hits it, it has high resistance -- it conducts electricity poorly. blcn fund fact sheetWebA photocell is basically an automatic switch that is controlled by sunlight during the daytime, and darkness during the night. The change from light to dark automatically activates the photocell to turn on the light fixtures that are wired to it. Example of Wiring a 120 Volt Photocell The Electric Circuit and Line Wiring Connections blc national guardThe photons need a minimum threshold frequency (a minimum amount of energy) to free electrons and produce a photoelectric effect, known as the work function. In the example shown here, the violet photons have enough energy to knock out electrons, but the red photons don't. See more Photo: A typical light-dependent resistor (LDR).
