直流電源有正、負(fù)兩個(gè)電極，湖南菊水直流電源哪個(gè)品牌好，正極的電位高，負(fù)極的電位低，當(dāng)兩個(gè)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，湖南菊水直流電源哪個(gè)品牌好，從而在外電路中形成由正極到負(fù)極的電流。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(dòng)。 </p> <p> 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，湖南菊水直流電源哪個(gè)品牌好，單靠電荷所產(chǎn)生的靜電場(chǎng)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(jiǎn)稱為“非靜電力”）使正電荷由電位較低的負(fù)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(gè)電極之間的電位差，從而形成穩(wěn)恒的電流。直流電源和交流電源的區(qū)別。湖南菊水直流電源哪個(gè)品牌好</p><div

電源的特征量表現(xiàn)電源本身的一個(gè)重要特征量是電源的電動(dòng)勢(shì)，它等于單位正電荷從負(fù)極通過電源內(nèi)部移到正極時(shí)非靜電力所作的功。當(dāng)電源給電路提供能量時(shí)，所供給的功率P等于電源的電動(dòng)勢(shì)E與電流I兩者的乘積，P=E I。 </p> <p> <br /> </p> <p> 電源的另一個(gè)特征量是它的內(nèi)電阻(簡(jiǎn)稱內(nèi)阻)R0，當(dāng)通過電源的電流為I時(shí),電源內(nèi)部損耗的熱功率(即單位時(shí)間內(nèi)產(chǎn)生的焦耳熱)等于R0I。 </p> <p> 當(dāng)電源的正、負(fù)兩極沒有連通時(shí),電源處于斷路(開路)狀態(tài)，這時(shí)電源兩電極之間的電位差在量值上即等于電源的電動(dòng)勢(shì)。在斷路狀態(tài)下，不發(fā)生非電能與電能的相互轉(zhuǎn)換。當(dāng)把負(fù)載電阻接到電源的兩極上以構(gòu)成閉合回路時(shí)，通過電源內(nèi)部的電流從負(fù)極流到正極，這時(shí)，電源所提供的功率E I等于輸送到外電路的功率U I(U是電源正極與負(fù)極之間的電位差)與內(nèi)電阻中損耗的熱功率R0I之和，E I=U IR0I。于是，當(dāng)電源向負(fù)載電阻提供功率時(shí)，電源兩極間的電位差U=E-R0I。 </p> <p> <br /> 湖南菊水直流電源哪個(gè)品牌好進(jìn)口線性直流電源那個(gè)品牌好？</p><div
