- Example: "My sister is in an LDR with her boyfriend who lives in another country."
2. Light Dependent Resistor:
In electronics, LDR stands for a Light Dependent Resistor, also known as a photoresistor. This is a resistor whose resistance decreases with increasing incident light intensity; in other words, it exhibits photoconductivity.
-
Characteristics:
- The resistance of an LDR decreases when the intensity of light increases.
- Used in light-sensitive circuits.
- Applications include street lights, burglar alarms, and camera light meters.
3. Less Developed Region:
In some economic and geographical contexts, LDR can stand for Less Developed Region. This refers to a region with a lower level of economic development compared to other regions.
