Last month we explored noise of the non-inverting amplifier but I dodged the issue of the feedback network’s noise contribution. A reader, Jim, challenged me—he wanted more detail. So what about the ...

In this article we talk about resistors in parallel, the equivalent resistance and the current divider rule for parallel connection of resistors. Let’s consider this circuit: In circuit 1 we have two ...

If you enjoy running, you’re bound to be disappointed with the current conditions that prevent you from getting out. Whether it’s raining or snowing, the temperature can be either too hot or too cold ...
