WebBipolar Transistors are current regulating devices that control the amount of current flowing through them from the Emitter to the Collector terminals in proportion to the amount of biasing voltage applied to their base terminal, thus acting like a current-controlled switch. WebExpression for Collector current With the above idea, let us try to draw some expression for collector current. Along with the emitter current flowing, there is some amount of base …

WebVCC = IBRB + VBE Therefore, IB = (VCC - VBE)/RB For a given transistor, VBE does not vary significantly during use. As VCC is of fixed value, on selection of RB, the base current IB is fixed. Therefore this type is called fixed bias type of circuit. In the Collector circuit Apply KVL, we get VCC = ICRC + VCE Therefore, VCE = VCC - ICRC WebBy combining the expressions for both . Alpha, α. and . Beta, β. the mathematical relationship between these parameters and therefore the current gain of the transistor can be given as: Where: "Ic" is the current flowing into the collector terminal, "Ib" is the current flowing into the base terminal and "Ie"

WebThe electric current produced at the collector region is primarily due to the free electrons from the emitter region similarly the electric current produced at the base region is also primarily due to the free electrons from emitter region. Therefore, the emitter current is greater than the base current and collector current.
