The transformation of the power landscape involves more than just generation. The distribution of electricity is being changed as well, with technology designed to make electrical systems safer, more ...

Racking in or out a power circuit breaker is simple, right? Although this task sounds pretty straightforward in theory, that’s not always the case. In fact, during years of field work related to ...

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 ...

If the power source is a listed Class 2 transformer or listed Class 2 power supply — or it’s in listed equipment marked to identify the Class 2 power source — you’ve got a Class 2 circuit between the ...

EcoWatt Power Saver revealed: discover how this plug-in energy device enhances home power flow, supports efficiency, and ...

As electronics applications continue to become more compact, powerful, and versatile, the final system demands and complexities of mobile and stationary devices also are becoming increasingly ...

Silicon MOSFET power transistors have been a mainstay of power-supply design for years. And while they’re still widely used, gallium-nitride (GaN) transistors are gradually replacing MOSFETs in some ...

Accidentally spilling a cup of coffee over a power strip will, at best, probably cause the connected equipment to stop working. On the other hand, such water-related electrical mishaps could lead to ...

One of the biggest challenges for wireless sensor networks is that of power. Solar panels usually produce less power than you hoped, especially small ones, and designing super low power circuits is ...

If you’ve ever tried to make a really low-power circuit — especially one that runs on harvested power — you have probably fallen into at least a few of the many traps that await the unwary in this ...
