    You need to assume values of Beta and Vbe for the transistor.

    The basic equations are ....

    Ib=(Vc-Vbe)/Rb ......................(1)
    Vc=Vs-(1+Beta)xIbxRc .............(2)

    and

    Ic=Beta x Ib

    Where Vc is the collector voltage, Vs is the supply voltage, Rb is the base resistor [100k] and Rc is the collector resistor [10k].

    Solve (1) & (2) for Ib by eliminating Vc and using your assumed values for Beta and Vbe.

    Also leo1_dany, please start a new thread instead of using an old thread. It frustrates members to see this happen.
