Finding Current and Potential Difference in a LCR Circuit

  1. Nov 2, 2009 #1
    1. The problem statement, all variables and given/known data
    There is a circuit, with the L and R in parallel and then there is a capacitor as well. There is a switch and a battery source. The E = 12 V and R is 1.37ohms. The switch is closed and the capacitor is uncharged and all currents are 0

    2. Relevant equations
    That's what I am having problems with, I though the equations for current was:
    L: E/R (1-(e^-t/(L/R)))
    C: E/R (e^-t/(RC))
    R: V/R

    But I was not given the L, so I don't really think those are the right forumlas, and I don't know where to try and look for the formulas.
