Capacitance Objective: In this experiment, we study how the capacitance of a parallel plate capacitor depends on separation distance. We also explore how the potential, charge, and equivalent capacitance changes when connecting capacitors in series and parallel Theory: Capacitance of a device determines how much charge it can hold at a given potential.
