2. Based on the diagrams that you have plotted, find the maximum charge and maximum current. max (V): max (4): Note that V is usually the potential difference at ? = 0 ? and is the current at ? = 0. 3. Determine half-maximum potential difference \\ , (V) and half-maximum current / , (A) Vva ( V): Iva(A): Note: V = V max 2 and I max /2
