Light Dependent Resistor Circuit Symbol. Light dependent resistor ldr the resistance of a ldr depends on light intensity. A rectangular box and the older zig zag line resistor circuit symbols.
At low light levels the ldr has a high resistance. The more the intensity of the light falling on the light dependent resistor the lower will be the value of resistance. As the light intensity increases the resistance decreases.
The light contains photon the particle of lights which carries the energy and having frequencies of a certain range.
At low light levels the ldr has a high resistance. The basic symbol of the light dependent resistor consists of a rectangle which symbolizes the resistor s function of the ldr. As the light intensity increases the resistance decreases. Light dependent resistor ldr the resistance of a ldr depends on light intensity.
