Mohammed AlMheiri 15/07/2014 0
You might have read this term before, but what does it mean?  What is a current limiting resistor? To answer this question, let me first ask you: how do you calculate current?well, the answer is simple: I = V/R now, suppose you have a 5v source, and a 10K ohm resistor, you get: I = 5/(10*10^3) = 0.0005A = 500uA Again, suppose you have a 5v source but a 1 ohm resistor, you get: I = 5/1 = 5A !!!!! t...
