When resistors are connected in series, the current through each ... total resistance of three resistors connected in parallel, we add a third resistor to the equation (and so on).

That’s a mouthful, but what he actually did was figure out what combinations of resistors can best be wired in parallel to achieve ... one 0603 surface mount resistor on top of another one ...

To calculate the resistance of the series resistor required, we need to look at the current and voltage values recommended by the LED manufacturer. Suppose a manufacturer recommends a maximum ...
