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.
