在稳恒电流电路中,凡流经同一电流的各电阻器互相串联,凡跨接在电路中共同端点之间的电阻器互相并联.但在复杂的混联电路中各电阻器的串联及并联关系不易分清.一般会用电学中如戴维宁定理或诺顿定理等方法来处理,但这些理论都不属中学物理课程大纲的范 In a steady current circuit, resistors flowing in series with each other through the same current, and resistors connected in parallel between the common terminals in the circuit are connected in parallel with each other. However, series and parallel connection of resistors in a complicated hybrid circuit Relationships are not easy to distinguish. They are usually handled by methods such as Thevenin Theorem or Norton Theorem in electricity, but these theories are not in the scope of the secondary school physics syllabus.
