I get somewhat annoyed when I hear engineers who have some real-world experience or exposure casually dismiss a component, especially a passive one, as “simple.” It may be simple in concept or ...

Determining the resistor values and assuring performance of the circuit associated with a photocoupler (also called an optocoupler or optoisolator) is simple in principle, but there are some points to ...

For simplicity's sake,let's just say there are two kinds of fuel injectors: peak and hold and saturated. The difference between the two has to do with resistance. Peak and hold (aka low impedance) ...
