Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...

The Royal Swedish Academy of Sciences has awarded the 2025 Nobel Prize in Physics to a trio of United-States-based scientists for work on quantum mechanic tunnelling. The award, announced by the Royal ...

The energy marketplace is one with plenty of nuances. Some homeowners might have solar panels installed on their roof, and in some areas, you're entitled to sell back excess energy to the utility ...

Three scientists won the Nobel Prize in physics Tuesday for research on the strange behavior of subatomic particles called quantum tunneling that enabled the ultra-sensitive measurements achieved by ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

Executives now expect to spend between $28 billion and $29 billion through 2028 and see opportunities for at least $4 billion worth of projects that aren’t yet in their plans.... Visibility gaps in ...

Three and four mark questions usually require longer answers. The answers here give lists of valid points that could be included in your answer. This page contains AQA material which is reproduced by ...

Abstract: In this paper, we present a method to solve inverse problems of electromagnetic circuit design, which are formulated as a topology optimization problem. Indeed, by imposing the magnetic ...

Abstract: A new FE-circuit coupled model is proposed to simulate the electromagnetic field interference (EMI) caused by terminal overvoltage and ground current of electric machines connected to ...

Three California-based scientists have been awarded the Nobel prize in physics for their observations of quantum mechanical tunnelling on the macroscopic scale. The discovery by John Clarke, Michel ...

Electrical power transmission networks are protected and controlled by medium and high-voltage circuit breakers. Breakers are meant to make and break the flow of electrical currents in transmission ...

Do not touch a person who is still connected to an electrical source because they can pass the electrical current on to you. Call 911 if someone has an electric shock, especially if they have signs ...
