This is design of indicator that is used to indicated AC current. This circuit could be wired into a 120vac power line, which feeds power to any load, ranging from 40 watts to 250 watts. It will turn on a LED light whenever current is being drawn by a load. It is especially useful for remote lights, where you may not be able to see if the lamps are receiving power. This is the figure of the circuit.
This circuit is built with low components. Consists of diode and resistor and displaying the indicator using lamp.
