This zigzag area separates the metal deposited areas into two regions. But there are few cases where the symbol used by the light dependent resistors depicts the resistor encased within a circle.

Light dependent resistor characteristics. When a light dependent resistor is kept in dark its resistance is very high. The material is deposited in zigzag pattern in order to obtain the desired resistance and power rating. Ldrs are light dependent devices whose resistance decreases when light falls on them and increases in the dark.
The symbol of the resistor and arrows as described above is used by the light dependent resistors in majority of their applications. This is evident in the case when circuit diagrams are drawn. It can be as high as 1012 w.
Here automatic night lamp circuit using ldr is given. Light dependent resistors ldrs or photoresistors are often used in circuits where it is necessary to detect the presence or the level of light. Here advantages and disadvantages of ldr are given.
Furthermore any doubts regarding light dependent resistor use please give your feedback by posting your comments in the comment box. Hope this article provides sufficient information regarding what is a light dependent resistor types of ldr working of ldr and applications of ldr. Other applications of ldr are light sensor relays fire alarm etc.
Please do comment and share it with your friends if your like the. The structure of a light dependent resistor consists of a light sensitive material which is deposited on an insulating substrate such as ceramic. This tutorial will help to study the trend of v i characteristics of light emitting diode.
The main application of the light dependent resistorldr is it is used as a variable resistor in the electronic circuits. They can be described by a variety of names from light dependent resistor ldr photoresistor or even photo cell photocell or photoconductor.
