Capacitors in Parallel
If we use two capacitors, we can power the lamp for longer. Let''s say capacitor one is ten microfarads and capacitor two is 220 microfarads. How do we calculate the total capacitance? Well, that''s very simple. The answer is 230 microfarads. The capacitors combine in parallel, so 10 + 220 equals 230 microfarads.
