The discovery and implementation of alternating current revolutionized the entire world little more than a century ago. Without it, we’d all have inefficient, small neighborhood power plants sending ...

For an undamped LC circuit excited by an AC voltage source through simple phaser equations, we come to see that the circuit becomes short circuited at the resonant frequency. However if we analyze the ...

In So you think you understand transmission lines, I offered a seeming paradox about a property of transmission lines. If you look at the input impedance of a uniform transmission line, open at the ...
