In a discussion on docking lights
I mentioned that I needed to smooth my dimmed LED cabin lights, and I ended up getting these smoothing capacitors:
SODIAL(R) 5 x 25V 1000UF 105C Radial Electrolytic Capacitor 10x20mm
Q1: Does the silver stripe with large "-" mean these are polarized and that's the negative side?
I'm going to install these in this circuit (where my "lamp" is a 12vdc LED light fixture that flickers when I'm plugged into shore power and charging):
Q2: Where does the capacitor go?
Looking at other sample circuits on the web it looks like it should go between the RED and BLACK wires - I'm thinking that the dimmer is a variable resistor and all of the diagrams show smoothing capacitors before an inline resistor. But I could also see putting it between the BLUE and BLACK wires.
Any guidance appreciated.
