1. The problem statement, all variables and given/known data In the following circuit, the ideal battery has an electromotro force of 12V, the resistances R1=4 ohms and R2 = 6 ohms. The capacito of 6x10^-6 F can be found discharged initially. The switch closes at t=0. Calculate the potential difference in the capacitor when t=2[itex]\tau[/itex] 2. Relevant equations q=q_o e^(-t/RC) [itex]\tau[/itex] =RC 3. The attempt at a solution I have tried many things, but nothing seems to be working.
