木材能导电吗?以下是其背后的原因

by Tobias

木材不知道会导电。然而,在某些情况下,它可以。在这个实用的提示中,找出木材是否以及何时能够导电。

这就是为什么木材会导电–在某些情况下

原则上,木材属于绝缘体,即导电性非常差的材料,如橡胶或塑料。然而,即使是木材也有可能导电。

  • 例如,木材是一种比空气更好的导体,这就是为什么闪电也会击中树木,从而通过它们导电。
  • 干燥的木材不导电。然而,由于水可以导电,潮湿的木材在低电压下是电的导体,可以用相位测试仪测试。
  • 尽管如此,与金属相比,木材不是一个好的导体,金属也被用于磁铁。
  • 与橡胶等绝缘材料相比,木材也不是一个好的绝缘体。
