【Abstract】 To analyse direct current circuit,Kirchoff law and Oham law are usually adopted.In this paper,a new method random walk method of charge,which based on random movement of free charge in circuit is iutroduced supposing that the free charge probably pass resistance,the distribution of current and voltage in circuit is achieved.Further more,the equivalency between the new and general mathod is proved.The current of bridge in unequlibrium wheatstone bridge and the equivalent formula of Y-connection and △-connection are deduced.更多还原
