A method and a position measuring apparatus that measures a position of a touch by an object on a device including the position measuring apparatus using an electrode unit for sensing a capacitance or voltage variation caused by a touch of the object and a control circuit unit for exchanging electrical signals with the electrode unit are provided. The method includes sensing a touch signal of the object on an independent channel connected to the control circuit unit through an independent connector; selectively driving a multi-channel disposed adjacent to the independent channel and electrically connected to the control circuit through a common connector, in response to the touch signal applied on the independent channel; and sensing the touch signal of the object using the multi-channel.
