所谓“并同串反”是指在电学混联电路里，与变化部分的电阻并联的各用电器上的电流强度、电压、电功率等的变化，跟变化部分电阻上的变化都相同，与变化部分电阻串联的用电器上各量的变化跟变化部分电阻上的变化均相反。对该法在电学判断问题中的应用，《中学物理》刊登的... The so-called “same-string-inverse” refers to the change in the current intensity, voltage, and electric power of each electrical appliance connected in parallel with the resistance of the changing part in the electrical hybrid circuit, and the change in the resistance of the varying part is the same as that of the change. The change in the amount of electrical resistance in the part of the resistors connected in series is opposite to the change in the resistance of the varying part. The application of this law to electrical judgment problems, published in “High School Physics”...
