Homework Help: Parallel Circuits

  1. Mar 25, 2009 #1
    a 3.3ohm resistor and another resistor are connected in parallel across a 3v battery. the current in the circuit is 1.41 A. Find the uknown resistance

    R=(1/3.3 + 1/x)^-1

    V=IR
    3v= 1.41A(R)
    R= 2.13 ohm

    this is where i got stuck...

    2.13 ohm= (1/3.3 ohm + 1/x ohm)^-1

    how do i go about finding x...

    the answer is 6 ohm but im curious how. :D ty
