This circuit is an alarm ammeter that can check whether the electric wire is connected to an AC power supply line. Just observe the display of an LED by placing the alarm ammeter close to a loaded electric wire if the LED blinks and/or simultaneously turns on with beeps meaning there is an AC power on the supply line.
