LDR

• light dependent resistors are dependent on light intenisty
• low resistance = bright light
• high resistance= dark
• ldr are used in outdoor lighting, burgular devices and automatic night lights
• connect a bulb in parallel to an ldr, the pd across both will be high when its dark and when dark the resistance of ldr will be high
• the bulb will get brighter as room got darker when connected across an ldr
