Sentences with phrase «allowing electrical currents»

Superconductors are materials that, when chilled, allow electrical current to flow freely, with zero resistance.

The wires rapidly absorbed the gas and swelled slightly, which closed miniscule gaps and allowed an electrical current to flow more easily.

The fantastic attention to detail that made this 10 - speed so likeable is obvious in other systems as well, like the ZL1's magnetorheological dampers that now use two internal coils instead of one to reduce inertia and improve reaction times, as well as a dual - wire system that allows electrical current to not only go in but also be pulled out of the fluid - filled damper for 40 percent faster damping response.

(PhysOrg.com)-- Electronic devices can't work well unless all of the transistors, or switches, within them allow electrical current to flow easily when they are turned on.

Not exact matches

When Joachim and Gimzewski moved the STM tip down, slightly flattening their buckyball, the molecule's electrical resistance dropped 100-fold, allowing the current to flow more easily from the STM tip to the metal surface.

The improvements could allow the rectennas — which convert electromagnetic fields at optical frequencies directly to electrical current — to operate low - power devices such as temperature sensors.

A small electrical voltage applied to one electrode — called the «gate» — increases the electrical conductivity between two other electrodes, allowing a large current to flow from one to the other.

This current can be tapped and amplified by the radio or television receiver, allowing power and information to be communicated over large distances without direct electrical connection.

The fact that the protective aluminum oxide layer is not incorporated on the outside, as often attempted by other researchers, also makes it possible to apply a broad range of materials on both sides of the solar cell and allows the maximum penetration of light in the perovskite layer and thereby the optimum utilization of electrical current.

The ideal TE material combines high electrical conductivity, allowing the current to flow, with low thermal conductivity, which prevents the temperature gradient from evening out.

As a result, the engineered quantum dots feature nearly complete suppression of Auger effect's heat loss, and this allows for redirecting the energy released by the electrical current into the light - emission channel instead of wasteful heat.

Liesbeth Venema says transistors are «electrical switches that either allow current to flow or not, and nothing in between» (5 August, p 33).

The one big difference between the two is BP's natural band gap, allowing the material to switch its electrical current on and off.

The researchers discovered that application of a weak electrical current via the scalp helps align different areas of the brain, synchronizing brain waves and allowing the areas to maintain the same beat.

But making use of functional MRI for imaging the brain allowed the researchers to reveal changes in activity while being stimulated, with the flow of information being potentially modulated by the electrical current.

First of all, this exact charge level does not stress the battery's cells, yet it still allows it to slowly discharge itself while waiting for the impatient user to provide a steady flow of electrical current.

Precisely controlling the electrical current that flows through the coil allows the driver to translate the electronic source into standard music and other audio.
