Sentences with phrase «carry electric current»

Turn on a magnetic field, and the material's ability to carry an electric current skyrockets or plummets in response.

Like all semiconductor diodes, LEDs release energy at the boundary between two regions doped with different impurities, where the electrons that carry electric current in one region meet the «holes» that carry it in the other.

Here, wires carry electric current into bottles filled with water and microbes.

But when the researchers characterized the electronic properties of their new substance — a combination of lanthanum, oxygen, iron and phosphorus — they found that below four kelvins, or — 269 degrees Celsius, it lost all resistance to carrying an electric current; that is, it superconducted.

These are materials that can carry electric currents without disruption.

Not exact matches

We know electric fields can be used to push the microrobots in any direction, like a boat carried by the ocean's currents, but in this paper we're exploring how those same fields can be used to help the robot detect obstacles and navigate around them,» Kim said.

A spin wave can be thought of as similar to an ocean wave, which keeps water molecules in essentially the same place while the energy is carried through the water, as opposed to an electric current, which can be envisioned as water flowing through a pipe, said principal investigator Kang L. Wang, UCLA's Raytheon Professor of Electrical Engineering and director of the Western Institute of Nanoelectronics (WIN).

The reason for this is that new current - carrying charges within the material are liberated by the electric field, thus increasing the conductivity.

At issue has been an accurate prediction of the size of the «bootstrap current» — a self - generating electric current — and an understanding of what carries the current at the edge of plasmas in doughnut - shaped facilities called tokamaks.

Output figures of the TwinPower Turbo 4 - cylinder and inline - 6 engines in the 528i and 535i remain unchanged at 240 and 300 horses, respectively, and the gas / electric ActiveHybrid 5 also carries over at its current 335 - horse total.

Electric currents are one way that this energy from magnetic reconnection is carried through the system.
