Question

LDR circuit diagram uses?​

Answer 1

The LDR circuit diagram works like this: When it's dark, the LDR has high resistance. This makes the voltage at the base of the transistor too low to turn the transistor ON. Therefore, no current will go from the collector to the emitter of the transistor.
