Physicists from Trinity College Dublin and the Universidad Complutense of Madrid have made a peculiar discovery in which energy moves from a colder to a hotter region. They describe how a quantum ...

Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

The term hot loop is relevant whenever switching regulators and their electromagnetic compatibility (EMC) are involved. This topic especially comes up in the optimization of trace routing on printed ...

The vast majority of bearing failures in electric motors and electric motor-driven equipment are due to mechanical and thermal causes. However, currents that flow through induction motor bearings can ...
