More on the ``skin effect''
As previously mentioned, the skin effect is where alternating current tends to avoid travel through the center of a solid conductor, limiting itself to conduction near the surface. This effectively limits the cross-sectional conductor area available...
Inductor quirks
In an ideal case, an inductor acts as a purely reactive device. That is, its opposition to AC current is strictly based on inductive reaction to changes in current, and not electron friction as is the case with resistive components. However, inducto...
Parallel resistor-inductor circuits
Let's take the same components for our series example circuit and connect them in parallel: (Figure below) Parallel R-L circuit. Because the power source has the same frequency as the series example circuit, and the resistor and in...
Series resistor-inductor circuits
In the previous section, we explored what would happen in simple resistor-only and inductor-only AC circuits. Now we will mix the two components together in series form and investigate the effects. Take this circuit as an example to work with: (...
AC inductor circuits
Inductors do not behave the same as resistors. Whereas resistors simply oppose the flow of electrons through them (by dropping a voltage directly proportional to the current), inductors oppose changes in current through them, by dropping a voltage d...
AC resistor circuits
Pure resistive AC circuit: resistor voltage and current are in phase. If we were to plot the current and voltage for a very simple AC circuit consisting of a source and a resistor (Figure above), it would look something like this: (Figure ...
