Investigating the Capacitance of a Parallel-Plate Capacitor Using a Reed Switch Objective: To investigate the factors which affect the capacitance of a parallel-plate capacitor using a reed switch. Apparatus: One reed switch, one signal generator, one pair of capacitor plates, polythene spacers, polythene sheet, one battery box, one voltmeter, one resistance substitution box, one light beam galvanometer, one 100g standard mass, connecting leads THEORIES Through the series of experiments, we would like to verify the following theories. 1. Charge and Applied Potential Difference As With the increase of voltage supplied by battery, the current is increased. Moreover, in a V-I graph, the slope m is the proportional constant fC. As we can obtain the generate our desired frequency f by a signal generator, we can obtain the capacitance . Capacitance is the amount of charges which can be stored per unit voltage applied to the capacitor. The unit is defined as farad (F). 2. Effect of Plate Separation and Area...
