1. The problem statement, all variables and given/known data The problem gives a graph of Emf versus time, in a circuit consisting of capacitor C and voltage source e. It asks to draw the time dependence of the current I in the circuit. 2. Relevant equations The graph looks like a trapezoid, positive slope starting at Emf=0 t=0, getting to t1 where the slope becomes 0, until t2, where it becomes a negative slope, and travels to t4 where it reaches Emf = 0 3. The attempt at a solution I know for Ohms law it states V = I/R, but there isnt a Resistor in the circuit given. Would this just show that the current graph should look exactly the same as voltage graph? Please help, thank you.
