A collaborative research team led by Prof. Ma Yanwei from the Institute of Electrical Engineering (IEE) of the Chinese Academy of Sciences (CAS), has shattered records in the current-carrying ...

Equipment: Two square U-shaped wires, a Plexiglas frame and a Xantrex HPD 15-20 power supply. What it does: The current carrying wires attract and snap together or repel each other depending on the ...

If you want to measure resistance and you know Ohm’s law, it seems like you have an easy answer, right? Feed a known current through the thing you want to measure and read the voltage required. A ...

The narrowest conducting wires in silicon ever made – just four atoms wide and one atom tall – have been shown to have the same electrical current carrying capability of copper, according to a new ...
