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 ...

As the story goes, the rock band AC/DC took its name from a label on an old sewing machine in the Young brothers’ home. It must have meant that the machine could run on either alternating-current or ...

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 ...

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 ...

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.

Fuses protect against overcurrent events by melting their elements and opening the circuit. Fuses must be applied at or below their specified voltage rating, which differs between ac and dc current.

Here is a simple 12 volts DC to AC inverter circuit. This 120V AC power source is built with a simple 120V:24V or 110V:24V center-tapped control transformer and four additional component. This circuit ...

You can't live without your smart phone charger. I understand that. However, the charger needs a DC supply. DC stands for Direct Current (this means that you can't say "DC Current" - that would be ...
