由欧姆定律及并联电路的电压、电流关系，不难推导出两电阻并联的关系式告，在此基础上，我们稍加证明便可得到如下推论．推论“两（不等值）电阻并联，并联的总电阻小于最小的电阻且大于最小电阻的一半．”证明两电阻并联，由关系式瓦“言得到，亡＞古，即评＜凡·RZ’”—“ From the voltage and current relationship of Ohm’s law and parallel circuits, it is not difficult to deduce the relationship between two resistors in parallel. Based on this, we can prove the following inferences with a little proof. Inferred that “two (non-equivalent) resistors in parallel, the total resistance of the parallel is less than the minimum resistance and greater than half of the minimum resistance.” Prove the two resistors in parallel, by the relationship between the tile “declared, died> ancient, that is, assessment” Van RZ ’“-”
