12v Ldr Relay Circuit Diagram. Therefore no current will go from the collector to the emitter of the transistor. Ldrs or light dependent resistors are very useful especially in light dark sensor circuits.

A half wave rectifier with only one diode is used. A voltage supply is given to the load. Therefore no current will go from the collector to the emitter of the transistor.
The resulting voltage is far from flat but the circuit does not need more.
The resulting voltage is far from flat but the circuit does not need more. A half wave rectifier with only one diode is used. A 230v ac supply for both the bridge rectifier. Ldrs or light dependent resistors are very useful especially in light dark sensor circuits.
