The resistive elements in the bulbs of the series circuit obey Ohm's Law, which states that the voltage across a resistive element equals the resistance of the element times the current flowing ...

Electric circuits often consist of several elements, some combined in series and others in parallel. The methods used to analyze series and parallel circuits can be combined to analyze these ...

There’s an in-depth tutorial of the classic series diode that’s the simplest of all power protection circuits. There’s not much to it – just a diode that provides reverse polarity protection.

This article discusses Loudspeaker Impedance and the load an amplifier sees if you wire speakers in series or parallel. We discuss the math and expected SPL differences as well as pros/cons of each.
