The key concepts you need to remember are: The analysis of an AC circuit mostly occurs at a single frequency with a sine wave input. Imaginary numbers aren’t imaginary.

Extension cords and power strips are fine for everyday devices, but using them with certain appliances - especially in summer ...

The circuit in Figure 1 provides a low-cost, isolated ac-line monitor that measures ac-line-voltage level and has some other unique capabilities. The analysis of the circuit is straightforward: When ...

How it Works? To design an Inverter, many power circuit topologies and voltage control methods are used. The most important aspect of the Inverter technology is the output waveform. To filter the ...

The asymmetrical short circuit current waveform can be broken down into two components: 1) a unidirectional (DC) component; and 2) a symmetrical alternating (AC) component.

The Variety Podcasting Brunch at SXSW featured a live-taping of the podcast Awards Circuit, with Sean Evans, host of “Hot Ones”; Rhett McLaughlin and Link Neal, the hosts of “Good Mythical ...

To understand common-mode noise, you need insight into how VFDs imitate a three-phase AC waveform. First, the frequency of the mimicked waveform is not what develops the noise.

What is the ideal temperature to set your AC to – for comfort or for energy efficiency? If you don’t have AC, what methods do you use to stay cool amid record-setting heat waves like this one?

Americans are scrambling to buy AC units, fans, cooling mats and other products to help beat the heat, as temperatures soar to record highs across the country.
