- It remains constant
Study Notes
Light Dependent Resistor (LDR)
- When light falls on a light dependent resistor, its resistance decreases.
- In dark conditions, the resistance of a light dependent resistor is high.
- When a light dependent resistor absorbs light, its resistance decreases, making it more conductive.
