Ok I have a small problem with capacitors, namely a lack or knowledge, at this moment I’m building a small power supply for a speed controlled electric motor using a LM338 which has a cap on the input side 10,000uf 40v, I got a 10,000uf 35v and a 10,000uf 50v. I was wondering if either of these would do, the supply is 2x12v=24v but I have no understanding of how these things are worked out, is it done by simple rule of thumb or is there some critical calculation involved here, and in what way does it affect the circuit if I get this wrong?
Many thanks for being there for us.
