power）有正、負兩個電極，正極的電位高，負極的電位低，當兩個電極與電路連通后，能夠使電路兩端之間維持恒定的電位差，從而在外電路中形成由正極到負極的電流。單靠水位高低之差不能維持穩(wěn)恒的水流，而借助于水泵持續(xù)地把水由低處送往高處就能維持一定的水位差而形成穩(wěn)恒的水流。與此類似，單靠電荷所產(chǎn)生的靜電場不能維持穩(wěn)恒的電流，而借助于直流電源，就可以利用非靜電作用（簡稱為“非靜電力”）使正電荷由電位較低的負極處經(jīng)電源內(nèi)部返回到電位較高的正極處，以維持兩個電極之間的電位差，從而形成穩(wěn)恒的電流。因此，直流電源是一種能量轉(zhuǎn)換裝置，它把其他形式的能量轉(zhuǎn)換為電能供給電路，以維持電流的穩(wěn)恒流動。
