A resonance electric current detection apparatus is disclosed. The above apparatus comprises a detection unit which detects an electric current by a resonance of an inductor L and a capacitor C and outputs to a control unit, and a control unit which controls an electric current detected by the detection unit. With the above construction, It is possible to easily perform a LC resonance electric current control, a speaker network resonance control, an automatic gain control and a LED control by forming the detected resonance electric current as a load circuit or controlling a surge voltage which is generated in a non-load state. |
