1. It consists of two electrodes, one inside the other, separated by an insulator. 它由两个电极组成,一个在另一个的内部,由绝缘体分开。
2. An insulator is a poor conductor because it has a high resistance to such flow. 绝缘体是不良导体,因为它是对电流的通过呈高电阻的物质。
3. Oils and salts from the skin can degrade insulator performance, and contaminants in the air can be deposited on the insulator surface, reducing its resistance. 皮肤上的油脂和盐份能够降低绝缘体的性能,空气中的污染物可能沉积在绝缘体的表面,从而降低其电阻。
