PROBLEM TO BE SOLVED: To provide a current and voltage sensing circuit which is equipped with a voltage drop compensation function. SOLUTION: A method and a device are for sensing the current and voltage of a circuit by voltage drop. In one embodiment, the sensing circuit is equipped with a diode and a resistor which are coupled in series within a path for a current to be sensed, and the voltage between both ends of the series coupling is coupled to drive a light emitting diode (LED).
