The diode circuit can be given forward or reverse bias.Connected with forward ias,as shown in Fig.1-2b-2,drawn for a PNP transistor,current will flow from the bottom P to the middle N.If a second voltage is applied to the top and bottom sections of the transistor,with the same polarity applied to the bottom,the electrons already flowing through the middle N section will promote a flow of current through the transistor bottom-to-top.

二极管的电路可以得到正向或反向，连接向前，如图1所示- 2b干扰素- 2，一个PNP晶体管得出，电流将流入从底部P为中间N.如果第二个电压用于晶体管的顶部和底部的部分，与适用于底部，电子已通过中ñ部分流入将推动下，通过晶体管的电流流至顶部相同的极性。
