摘要： An electric current flow indicator senses electrical current flowing through an electrical device and produces a visible feedback to indicate proper operation. The current flow indicator has a voltage and current regulation circuit having first and second inputs connected to first and second conductors, respectively. The circuit converts an AC line voltage carried by an electrical supply cord into a limited low voltage DC current. A toroidal core inductor coil and at least one current indicating LED are connected to the circuit. The first conductor passes through a center of the inductor coil. A transistor amplifier is connected to an output of the inductor coil for energizing the current indicating LED when an electrical current conducts through the first conductor. The flow indicator can be integrated into an electrical supply cord, a male or female electrical cord end, a single or duplex electrical outlet, or a universal plugin adapter.
