    sir i am confused i know that thevenin theorem is use to find resistance and voltage

    convert ac in to dc circuit

    if rectifier+ resistor+capacitor+load

    can i apply thevenin theorem here to find the load resistance and voltage

    You can apply Thevenin to the part of the circuit that is linear. Thevenin is a "linear" theorem. For example if you have a voltage source Vs with a voltage divider R1 (series) and R2 (parallel to ground) and let's say you have a diode across R2. It is possible to apply Thevenin's theorem to the circuit "seen" by the diode so that the thevenin voltage VTH=(R2/(R1+R2))*Vs and RTH=R1||R2.
