Here I am with my geared motors to use for my C.C. Artificially Intelligent Rover and a bag full of new old style floppy drive ribbon cables with 10 pin 0.1" 2x5 IDC headers on both ends. While scratching my chin, I wondered "How much current can I push thru those tiny wires?" Once again, I turned to my trusted Google Search engine and input the following search string: "what is amp rating of ribbon cable?" Choosing to open the result from AVR Freaks seemed the obvious choice. Although somewhat long winded, the discussion covered the sought after info and shared some EE insider tricks. The answer was a surprising 1.1 amps and one really should derate that value for safety's sake; therefore, 0.5 amp is a really good answer since my geared motors are rated 0.1 amp.
