Why don't your Christmas lights work? Sadly, in the event of a string of lights going out on your tree, replacing the strand is usually the best option. It's pretty difficult to find that one bulb ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

In my previous article on photovoltaic (PV) systems (“The Highs and Lows of Photovoltaic System Calculations” in the July 2012 issue), I went through methods to calculate the changes in voltage due to ...

The current flowing in a series circuit is the same everywhere. Figure caption, A series circuit with two bulbs and one cell. The ammeter will read the same at points 1, 2 or 3. In series circuits, ...

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 ...
