Homework Help: BJT analysis

  1. Oct 31, 2016 #1
    1. The problem statement, all variables and given/known data
    Find Vc, Vb, Ve, Ib, Ic, and Ie
    Vbe for all circuits is 0.7V

    2. Relevant equations

    3. The attempt at a solution
    Vc = 10V
    Ib = (Vcc-Vbe)/(Rb + (Beta+1)Re) = 9.3/(105100) = 0.0885mA
    Ic = Beta*IB = 4.425mA
    Ie = Ic + Ib = 4.5135mA
    Ve = IeRe = 0.45135V
    Vb = Ve + Vbe = 1.15135V

    Is this correct?
