Voltage amplifier transistor circuit (diagram provided)

  1. Apr 29, 2008 #1
    Hello guys,

    I'm struggling with these type of circuits. Here is my question. I have drawn a diagram in paint

    [​IMG]

    When the input AC voltage= 0 v the collector current is found to be 1.0 mA. The current gain of the amplifier is 200. There must be 0.7 V between B and E before current can flow from the collector to the emmiter. What is the resistance of Rb

    Well I know that Ai= Ic\Ib and I can find Ib but I don't know how to use this information. My understanding of series and parallel circuits is good but I don't know how this type of circuit works. If anyone can give me a detailed step by step of how this system works I'll be reallly really greatful :smile:
