Can speaker wires be used for power transmission? Answered
I am making my own bicycle light and I decided to use 18 gauge speaker wire. Speaker wire works well because positive and negative are glued together in the insulation. It makes for a cleaner wiring job. I am using the RCA plugs as well. The light runs at 4.2 volts and 1.5 amps. Speaker wire is not designed for power transmission but I can use it for that purpose can't I? Do RCA jacks have a significant amount of resistance?
