Abstract
The present invention relates to a current sensing resistor made by an electrically conductive metal plate, and the current sensing resistor comprising: a middle portion; a first portion with a first slot located at one side of the middle portion; and a second portion with a second slot located at the other side of the middle portion opposite to the first portion; wherein each of the first and second portions is divided into a current terminal and a sensing terminal by the first and second slots respectively, and the current terminals of the first and second portions have a length greater than that of the sensing terminals of the first and second portions; characterized in that the middle portion has a middle slot and the length of the middle slot can be used for controlling the stability of resistance for the current sensing resistor.
