中文摘要：在稳压电源电路中，串联型稳压电源的调整管与负载串联，负载电流全部流经调整管，而晶体管的过载能力较差，一旦输出端过载或短路，输入电压全部加在调整管集---射极间，其电流剧增，使调整管猛烈发热，如果此时没有过流保护措施，调整管就要被烧坏，电源整流管也将受到巨大威胁或损坏。

If you change the diode current by changing the resistance value of Rbias, then the transistor's emitter current will follow suit, because the emitter current is described by the same equation as the diode's, and both PN junctions experience the same voltage drop.
