1. The problem statement, all variables and given/known data a) How much energy in microjoules is stored in the capacitor at t=500 micro sec b) Repeat (a) for t=infinite 2. Relevant equations Will be on attachment 3. The attempt at a solution I am not sure how to approach the problem.. The graph shown is a graph of amps respect to time. So the tangent line to the function curve is joules?
