An electrical contractor in Austin, TX, posted a super-informative blog post about understanding AC and DC electrical currents. This is what the differences boil down to: "DC" means "direct current".

The harnessing of electricity has played a pivotal role in human history and has exponentially expedited our growth as a species. Since becoming a household commodity in the late 19th century, ...

Significant complications arise when trying to get your power supply working from a wall outlet. Making a dc voltage from an ac source means you will have to rectify the ac voltage to get a dc bus.

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.

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...

It is important to understand the characteristics of both AC and DC measurements, as both can probe the cure state of thermosets and composites, so it is vital to have a clear outline of the benefits ...
