I have a simple application where a 6V, 2A DC power supply is driving 4 hobbyist-grade servos. In most cases this is adequate, but there are cases (when all servos are suddenly loaded) when I think the power draw will exceed 2A for a short period of time.
It was suggested to me that I should use a capacitor between my power source and the servos in order to handle this kind of transient load. Unfortunately the suggestor didn't know how this would actually be implemented. I tried the University of Google, but mostly came up with videos of giant capacitors being used to dramatically explode things.
Could someone point me in the right direction, or give me a simple circuit example of how I would do this. Is it as simple as wiring a capacitor onto the positive lead?
What calculations should I make to determine the appropriate capactitor size? For example, if I wanted to sustain a peak of 3A for 5 seconds.
