Summary:A peripheral device configured to be plugged into an audio jack of an electronic device includes an audio plug having an input terminal; a load electrically connected to the input terminal of the audio plug and configured to draw a first amount of current; a variable resistor electrically connected to the input terminal; a sensor configured to measure a voltage at the input terminal or an amount of current flowing into the load; and a controller that receives a signal from the sensor and is configured to control a resistance of the variable resistor such that a sum of the first amount of current and a second amount of current flowing through the variable resistor is substantially equal to a predetermined current value.
