This tutorial will showcase how inductance, capacitance and resistance affect alternating current. A circuit may have the alternating current through it and the voltage across it rising and failing ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

In the December 2008 issue of EC&M, we talked about calculating the inductive reactance of conductors that are in close proximity to (or touching) one another. We also noted that the inductance and, ...

We’ve been talking about speaker cable and have covered resistance and capacitance in past columns, which are also posted in the Wired for Sound index page. There ...

Inexpensive scientific and engineering calculators have pretty much eliminated the need for nomographs that embody complicated relationships that would prove cumbersome or difficult to calculate ...

Resistors aren’t resistors – at high frequencies, that is. Many designers don’t realize that parasitic elements in real components affect their values. When frequencies reach hundreds of megahertz, ...

The four basic capacitor types. The key parameters involved in selecting the right capacitor for automotive designs. Advantages and limitations of electrolytic and electrostatic capacitors. Choosing a ...

Inductors range from RF coils used in communications through switchmode inductors used in power supplies and differential and common mode inductors in EMI filters. As switchmode power supply designs ...
