的），電(dian)荷(he)導(dao)體里本來就有，要產生(sheng)電(dian)流只(zhi)需(xu)要加上(shang)(shang)電(dian)壓即可，當電(dian)池兩極(ji)接(jie)上(shang)(shang)導(dao)體時為了(le)產生(sheng)電(dian)流而把正負(fu)電(dian)荷(he)釋放出去，當電(dian)荷(he)散盡時，也(ye)就荷(he)盡流（壓）消了(le)。干電(dian)池等叫做(zuo)電(dian)源。

通過(guo)變(bian)壓(ya)器(qi)和整流(liu)(liu)器(qi)，把交(jiao)流(liu)(liu)電(dian)變(bian)成直流(liu)(liu)電(dian)的裝置(zhi)叫(jiao)做整流(liu)(liu)電(dian)源(yuan)。能提供信號的電(dian)子設備叫(jiao)做信號源(yuan)。晶(jing)體三極管能把前面送來(lai)的信號加以放(fang)大，又把放(fang)大了的信號傳送到后(hou)面的電(dian)路中(zhong)去

。晶(jing)體三極管對后面的電路來說，也(ye)可以看做是信號源。整流(liu)電源、信號源有時也(ye)叫做電源。
