I need some help building a full wave bridge rectifier. I need to install a resistor(s) (apparently) to get potential difference, but I don't treacly understand why. Anyway, without explaining the physics, please could anyone tell me what resister value in Ohms and what wattage value would I need if I installed a resister in position R0, before the LED's (all of which are 1.8w and approx 160mA), or should I install a resister at positions R1 R2 and R3.
Ideally, I just want one, but can you advise on the specs please and how to calculate if the LED ratings change?
Please look at attached diagram
