style="font-size:16px;">電流法的間接測(cè)量實(shí)際上是用測(cè)電壓來(lái)?yè)Q算電流或用特殊的方法來(lái)估算電流的大小。欲測(cè)晶體管該級(jí)電流時(shí)，可以通過(guò)測(cè)量其集電極或發(fā)射極上串聯(lián)電阻上的壓降換算出電流值。這種方法的好處是無(wú)需在印刷電路板上制造測(cè)量口。另外有些電器在關(guān)鍵電路上設(shè)置了溫度保險(xiǎn)電阻。通過(guò)測(cè)量這類電阻上的電壓降，再應(yīng)用歐姆定律，可估算出各電路中負(fù)載的電流的大小。若某路溫度保險(xiǎn)電阻燒斷，可直接用萬(wàn)用表的電流檔測(cè)電流大小，來(lái)判斷故障原因。3．幾點(diǎn)說(shuō)明（1）遇到電器燒保險(xiǎn)或局部電路有短路時(shí)，采用電流法檢測(cè)效果明顯。（2）電流是串聯(lián)測(cè)量，而電壓是并聯(lián)測(cè)量，實(shí)際操作時(shí)往往先采用電壓法測(cè)量，安寧區(qū)口碑好的家電維修，安寧區(qū)口碑好的家電維修，在必要時(shí)才進(jìn)行電流法檢測(cè)，安寧區(qū)口碑好的家電維修。嚴(yán)禁大面積地采用代換試驗(yàn)法，胡亂取代。這不僅不能達(dá)到修好電器的目的，甚至?xí)M(jìn)一步擴(kuò)大故障的范圍。</span>

style="font-size:16px;">常聽到一些同志說(shuō)，“我基礎(chǔ)知識(shí)不好，這些東西還不懂，怎么去維修呢？”其實(shí)，許多日常的維修工作并不需要很高深的理論去支持,只要具備基本知識(shí)即可勝任有余。例如說(shuō)，一臺(tái)收錄機(jī)全無(wú)反應(yīng)(用交流供電時(shí))，用直流電(電池)接上一試，正常工作。這么一試，便可得知交流電源供電電路部分有故障。再用萬(wàn)用表一量，變壓器開路了。換上新品，通電試機(jī)，一切正常。這么簡(jiǎn)單的維修可以說(shuō)是人人都行，只是我們有些同學(xué)一直懶于去做，不肯動(dòng)手。導(dǎo)致他們不肯去干的原因是多方面的，其中很重要的一個(gè)就是，他們覺(jué)得自己不懂得理論，電路出</span><span style="font-size:16px;">了故障不知怎么去查找。而事實(shí)上，由于科技的進(jìn)步，制造水平的不斷提高，產(chǎn)品質(zhì)量也不斷提高，電器發(fā)生嚴(yán)重故障的機(jī)會(huì)已是很小，大量的都是使用不當(dāng)而引起的系統(tǒng)故障，接觸不良，保險(xiǎn)絲熔斷等小毛病，有些根本不用修，調(diào)幾下就可以復(fù)原。既然我們知道，電器發(fā)生大故障的機(jī)會(huì)并不多，那么在電器有故障時(shí)我們大可不必驚慌，只要細(xì)心觀察，加以分析，再測(cè)試確診，在許多情況下都可以排除故障。</span>
