FInding the current through a resistor in parallel with 2 other (nonequal) resistors

  1. May 24, 2009 #1
    How do you find the current through a resistor that is in parallel with 2 other nonequal resistors? I totally forgot how to do this.
    as an example, if

    E = 10V
    R1= 5ohm
    R2 = 10ohm
    R3 = 15ohm

    So, I know that 1/Req = 1/R1 + 1/R2 + 1/R3 = .533ohm

    and also know Inet = 10V/.533ohm = 18.76A

    but how do i get current going through R1???


    please help, and thanks


    PS --this is NOT a homework question even though i post alot of HW questions

    You have the voltage and resistance, just use Ohms law.

    So you use ohms law for each resistor and doesnt matter if its in parallel or in series with other resistors? (thats whats confusing me)

    Hint: You have too much information.
