And this something is called a dielectric – typically an insulating material like plastic or glass.

这种东西叫做绝缘体。通常，它是 它是一种绝缘材料，例如塑料和玻璃。

Initial investigations suggest the incident was caused by the piling of an insulating material on the roof which became heavier after it soaked up water from the rain.

初步调查表明，此次事故是由屋顶上堆积的绝缘材料在吸收雨水后变重引起的。

So by inserting an insulating material into our capacitor, we’ve increased capacitance and can hold more charge, and thus energy, for the same amount of voltage.

因此，通过在我们的电容器中插入绝缘材料， 我们增加了电容并且可以容纳更多的电荷， 从而在相同的电压下容纳更多的能量。
