All supernaturals, we got a natural resistance.

所有超自然物种都有天生的抵抗力。

Today we learned about batteries, and how terminal voltage results from the natural internal resistance of every real battery.

今天我们了解了电池，以及终端电压是如何由任何真实电池的自然内阻产生的。

Since most inductors have a natural resistance, we'll say that there's also a small resistor in series with the inductor and battery.

由于大多数电感器都有一个自然电阻，我们会说还有一个小电阻器与电感器和电池串联。
