5C30.35 - Capacitor - Lift a Mass
Completely charge the 1 Farad capacitor with either the Genecon generator or the 6 V battery. Disconnect the charging device and attach the capacitor to the motor. The motor will wind the string and lift the mass until the capacitor discharges enough to no longer run the motor. A 100g or 200g mass works well for this demonstration. If desired, the efficiency of the motor can be calculated by comparing the change in gravitational potential energy of the lifted mass to the initial energy in the charged capacitor.
