对于电桥问题,通常的求解方法有两种:其一是根据基尔霍夫定律列电压方程或电流方程进行解答;其二是根据三角形网络与星形网络的变化公式,对三角形网络与星形网络进行等效变换,这样也可使电桥问题得解.本文将要通过在电阻中找等势点,从而得出求解电桥问题的一种新方法.
For the bridge problem, there are two general solutions: one is to solve the voltage or current equation according to Kirchhoff’s law, and the other is to change the formula of the triangle network and the star network to the triangle network and the star. Equivalent transformation of the shape network can also solve the bridge problem. This paper will find a new method to solve the bridge problem by finding equipotential points in the resistance.
