When the lights go out, a portable generator can feel like a lifeline, but if you rush the startup, you can end up staring at ...

The other day, I was casually scrolling through Google when I stumbled upon a flood of dirt-cheap RC snubber circuit modules on various online stores. That got me thinking—it’s high time we talk about ...

Many loads are mainly resistive; thus, they’re rated in watts (i.e., true power). Simply stated, these loads have a very small reactive component, which means an apparent power rating (VA) would not ...

• Electrical power sources supply two types of power to inductive loads: real power in kW and reactive power in VAR. • Power-factor correction circuits can be either an individual style or of the bank ...

Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

Despite all of the attention devoted to low voltage, low operating, and quiescent currents, and low power in general, the reality is that many applications require more power during real “work” as ...
