Are there any considerations I need to make when designing the traces for these AC and DC circuits? I know that I need to make the traces wider where power is flowing, and I was going to try spacing ...

Here's an alternative to rewinding AC coils for operation on DC circuits. It's relatively simple - all it takes are a few calculations and a little bench testing. Want to skip the time and expense of ...

The previous tutorials featured resistors in direct current (DC) circuits wherein the voltage and current have been assumed to be of constant polarity, flow and direction. The voltage, current and ...

When picking a switch to use in electrical design, many people believe they can use any switch, provided its current rating is more than the maximum load in the circuit. This, of course, isn’t true.

When choosing a switch to use in an electrical design project, there is a perception that it is possible to use any switch, provided its current rating is greater than the maximum load in the circuit.

Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

When energy-efficiency costs come into play, more designers are opting for the electronically commutated motor rather than familiar AC and DC versions. For motor applications, engineers have several ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

Here's an alternative to rewinding AC coils for operation on DC circuits. Want to skip the time and expense of rewinding AC coils so they can operate on DC? Or are you won dering if it's even possible ...
