I need some help with an LED circuit. I have 48 LEDs wired in parallel, each with a voltage drop of 5V, operating at 40 mA, with a 12V supply. Should I use a single 175 OHM resistor for each LED? Should I split the LEDs into 24 pairs, each pair wired in series, using a 50 Ohm resistor? What would be the best design?
