Abstract

An electronic circuit for an electric appliance. In one embodiment, there is provided an electronic circuit for a battery-operated electric appliance, which can be inductively fed by an external electric power source, comprising a charging circuit for charging an accumulator (A), which encompasses a charging coil (L2) and a diode (D2), wherein the accumulator (A) is connected in series to the diode (D2) and the charging coil (L2), a light emitting diode (LED) as display for the charging process and/or charging status of the accumulator (A), wherein an end of the charging coil (L2) is connected to the cathode of the diode (D2) and the anode of the light emitting diode (LED) and the negative pole of the accumulator (A) is connected to the anode of the diode (D2).
