If you grew up with the 741 op amp 1, it was drilled into your head to balance resistances seen by the op amp inputs. Over time, with different circuit techniques and different IC processes, this may ...

Electricity powers everything from your phone to your refrigerator—but have you ever wondered how it’s controlled inside a ...

One of the standard methods used to measure load current is to insert a low-value resistor in the load line and sense the voltage across it, Figure 1, followed by an analog or digital implementation ...

Should I be concerened about screwing something up in a power supply by adding a resistor to the fan inside the power supply?<P>I'm trying to undervolt the fan a little.<P>(may be a double post.
