Capacitors are gadets that store energy until a large potential energy has been stored.
When it is achieved, the energy then leaps over and goes to the other side of the capacitor to finish the circuit. The amount of energy a capacitor holds are measured in Farads. Setup the series diagram, measure the capacitance, and record. Setup the parallel diagram, measure the capacitance and record. Setup the RC circuit diagram, measure the capacitance, the voltage, and record.
