Parallel capacitors array: A charged capacitor charges the others.

Parallel capacitors array: A charged capacitor charges the others. Discharge the circuit by closing all capacitor switches and placing the knife switch in the discharge position. Open all capacitor switches but one, then close the knife switch in the charge position. Now open the knife switch and notice the voltage on the projection voltmeter. At this point, throw the switches on the capacitor array, one at a time. Notice that the voltage decreases as you add more capacitance. The voltage should decrease fairly proportionally, because the capacitors have the same value. NOTE: Short the capacitors before putting away.
