A World That Cannot Be Explained by Resistance AloneIn Part 35, we stepped into the new world of alternating current. In DC ...

Using circuit simulating software like SPICE can be a powerful tool for modeling the behavior of a circuit in the real world. On the other hand, it’s not always necessary to have all of the features ...

If you want to measure resistance and you know Ohm’s law, it seems like you have an easy answer, right? Feed a known current through the thing you want to measure and read the voltage required. A ...

Analog Devices references guard shields around their op amps as well as the printed circuit traces [1]. These traces are called guard rings; they circle and shield critical circuits. Another ...

In this chapter the concept of waveguide input impedance (and admittance) is presented first. This is followed by a consideration of the input impedance (or admittance) relationships of a waveguide to ...

You have designed an op-amp circuit to measure a small voltage. The circuit gain is -10V/V, but it appears that the input impedance to the circuit is effecting the device as it is being measured. How ...

Intended as a textbook for electronic circuit analysis or a reference for practicing engineers, the book uses a self-study format with hundreds of worked examples to master difficult mathematic topics ...

Electricity does not choose “the path of least resistance,” but flows on all paths presented to it. The flow divides among those paths in inverse proportion to their impedances (those paths with lower ...
