    I have a parallel circuit with 3 resistors. I have the values of the resistors and the current value going into one resistor. I need to find the voltage supply and current supply. Any formulae or help please

    If you have three resistors in parallel, you know that the voltage across each resistor is the same. If you have the current through and resistance of one of the parallel branches, you then have the voltage across all three resistors. All that is left to do is divide that voltage by each resistor and you can obtain the current flowing in each resistor.
