    In a Series-Parallel circuit, how do you find the resistance and the current if only the voltage is given? 5 resistors in series and 1 resistor in parallel.

    R1= 3 ohm Voltage= 3V Current 1A
    R2= 5 ohm Voltage =1.65 current 0.33A

    R3= ??? voltage= 4 volts (parallel)

    R4= 4 ohm Voltage 1.32 Current 0.33
    R5= 1 ohm voltage 1 volt current 1A
    R6=3ohm voltage 0.99 current 0.33

    Your problem would be clearer and easier to solve if you could provide a sketch of the circuit.

    Your values seem uncoherent... the only possibility to underestand the problem is by designing the circuit...

    With your detail, I don't see your initial standard ... 5 resistors in series and 1 in parallel.

    I can see three branches in parallel, one single resistor, on with two in series, and one with three in series.

    If there is an associated drawing, post it.

    I also responded to this somewhere else. Your values do not make sense.

    Draw it. Use paint/Paintbrush, zip it, post it.

    You don't.

    Okay... R1 and R5 are in series with each other, yes? 1A each and 4v across the two of them.

    R2, R4, and R6 are in series as well... 1/3 amp each and about 4V across the three of them.

    If R3 is also in parallel, then there is no way to know current or resistance, save that R>0.

    If the above is wrong, then the numbers given are also wrong.
