Figure 2 below shows a capacitor of capacitance C is connected in series with battery of emf, E, a switch and a resistor of resistance R. When the switch is closed, charge Q flows through the resistor. E R. Figure 2 a) By using a formula, explain the difference between each cases ( if any) for: i) the energy delivered to the circuit by the battery ii) the final energy stored in capacitor. Justify your answer. b) You are given a number of capacitors are marked '50µF,25 V’. i) Explain the meaning by this marking. ii) Construct a circuit diagram, one in each case, to show how you would connect a number of these capacitors in order to obtain arrangements having the following specifications: I) 100µF,25 V II) 75 µF,50 V
