Today, we saw how circuit analysis can be used on any series and parallel configuration of resistors in a DC circuit.

今天我们看到了如何将电路分析用于直流电路中电阻的任何串联和并联配置。

Kirchhoff took laws we already knew – the conservation of charge and of energy – and established two rules for circuit analysis.

基尔霍夫采用了我们已经知道的定律——电荷守恒和能量守恒——并为电路分析建立了两条规则。

By now, thanks to our lesson on circuit analysis – and previous Crash Course Physics episodes – you know your way around a basic DC circuit.

到现在为止，多亏了我们关于电路分析的课程——以及之前的物理速成课程——你知道了基本直流电路的方法。

But, one of the best ways to understand how electricity works in a system like that, is through circuit analysis
