The carbon-are lamp, a very bright electric lamp used for spotlights, consists of two carbon electrodes (with) a high-current are passing between (it).
with后是附句,附句用来修饰two carbon electrodes。介词with之后可以是名词,也可以是个谓语成分,形容主体内在的东西,如: That is a cage with two birds inside it。 I have a bottle with the milk swirling like a tornado。 The running track with greenery surrounding its area is the one I like。 这个做法并没问题。
