Abstract: A cooking apparatus includes: a working coil, an inverter configured to output a resonant current to the working coil, a current detector configured to detect the resonant current and output a detection value corresponding to the resonant current, and a controller. The controller is configured to control the inverter to flow a first resonant current through the working coil, control the inverter to flow, through the working coil, a second resonant current having a frequency different from the first resonant current, and determine, based on a difference between a first detection value for the first resonant current and a second detection value for the second resonant current, whether a target object that is located adjacent to the working coil is a predetermined object.
