    Hi There,

    Im trying to build a simple transformer circuit (shown in the figure).
    The transistor gives me a perfectly amplified version of the 2v base input signal giving my an output of 10v but when connect the primary coil as shown in the diagram i get a voltage of around 4 volts across the primary coil.

    Does anyone know the reason for this and is there any way I can maintain the voltage when the coil is added

    Thanks

    Replace the 150Ω resistor with the primary coil.
