This article introduces a method of sampling and measuring DC current using the resistance of the wire itself, which can simply replace the current sampling resistance usually used in DC current measurement, making the wire itself a simple and reliable non-destructive sampling of large DC current Measuring sensor. Since there is no change to the original circuit state, the heating loss and connection points of the access sampling resistor are avoided, thereby greatly improving the reliability of the circuit
