组合电路假论：你怎么看在一个组合电路中增加电阻会影响电线中的电流和势位能.您能帮我回答一下你 我完全不懂物理 拜托了。potential difference就是电位差。这就纠正一下。
个人认为电阻增加，必定导致电流有变化。因为电压保持不变的话。电阻增加，电流就较少。至于电位差与电流强度的关系。这个好像比较复杂。两个的判断依据不一样。不好说。这是英文的作业 要说英文的 拜托您能把您说的翻译成英文吗。great, pushed little by little. but I will try to solve the problem.please be attentative to text hereibafter. in my personal view, if resistence is increased, it will definitely lead to a change of currency, because wheb voltage maintains ubchanged, the increase of resistence will lower the currency. As far as the relation between potential difference and currency, it is actually a little bit complicated. for the theorotical basis for these two definitions are not the same. so it is of uncertainty for me.
