    Hi I am Vasimavr and I was wondering if you could help me do my homework.

    For the circuit of the picture the values we know are:

    Vcc = 12,2V
    VBE = 0,7 V
    β = 500

    RE = 500 OHM
    RC = 2000 OHM
    R2 = 14 KOHM

    Find R1 so that the operating point Q of the transistor, to be in saturation.

    Thanks for your help.

    Hi Vasimavr

    the people here wont give you the outright answers, but will help you work your way through the problem
    Ok, so you must have been studying this subject in class

    What have you learnt so far about biasing transistors in general ?
    what formula do you think are appropriate to help you solve this question ?

    cheers
    Dave

    What is the definition of saturation (for a BJT), according to your course material?

    I find it a bit complecated exercise.... at theory only have the following

    The diagrams you posted in post #5, and the formula you posted in post #6, all relate to FETs, not BJTs!
