摘　　要：介绍一种新的方法———电荷无规行走法分析直流电路.给出该方法和常规方法等效的证明,并用此方法推导了惠斯通电桥非平衡时的桥路电流,以及Y型联接与△型联接的等效变换公式.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 iutroducod 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.
