onnected to the terminal leads. Use a multimeter to measure its resistance when light is shine on it and when it is placedin a dark place. This will help to enhance your knowledge of the concept as to how the LDR works.

Simple Light Dependent Resistor Description

The Light Dependent Resistor and a trimpot form a voltage divider which is used to apply bias to a transistor. As the LDR changes resistance the change in potential is detected by the circuit and the relay is activated. The PCB-mounted switch just interchangesthe trimpot & the LDR as far as the detection circuit is concer..................==> [ Click Here to Read More ]

Light dependent resistor(LDR), also called as Cadmium Sulphide (CdS) cell or photoresistor is a resistor whose value depends upon the incident light intensity. In darkness, the resistance of LDR becomes high and in light, the resistance gets low. The resistance variation phenomenon of LDR has been taken as a base for making circuits of LDR Engineering.



My question is that can wee use anything instead of light dependent resistor (LDR) ??..................==> [ Click Here to Read More ]

o the disk has a limitation. This limit now a days is 13Gb/sq. inch. So the hard drive storage density has to be limited to that extent. The storage density cannot be increased even though the technology to do so is available because of the read head limitation. Here comes the importance of extraordinary magnetoresistance. This property makes it possible to create hard disks of high density storage, because by using this property it is possible create read- write heads which can access the data from the high density storage disks which in normal case would not have been possible.
