Sentences with phrase «as electrical resistance»

Not exact matches

The researchers had a helicopter fly a giant transmitter loop over the landscape, inducing an electrical current in the ground, and measured the resistance to the current as far as 350 meters below the surface (see video below).

Superconductivity is at the heart of intensive research in physics, in particular because of its remarkable electronic properties, such as the absence of electrical resistance.

Researchers have found a way to trigger the innate, but previously hidden, ability of graphene to act as a superconductor — meaning that it can be made to carry an electrical current with zero resistance.

As a read head moves above bits of magnetic data, changes in the magnetic orientation of those bits alter the electrical resistance of electrons flowing through the sensor, translating the magnetic data into a stream of electrical pulses.

Older SOFC designs use the electrolyte layer as a structural support, but the thicker component has a higher electrical resistance, which entails higher operating temperatures to avoid power losses, Wachsman explains.

Strange metals include high - temperature superconductors, which have no electrical resistance at all below a critical temperature that is generally defined as above the boiling point of liquid nitrogen (196 °C).

On the other side, sensors can be added to measure pressure, temperature or electrical properties such as resistance.

These are materials in which all resistance to an electrical current disappears at temperatures ranging from near absolute zero to as «warm» as around — 170 degrees Fahrenheit -LRB--- 112 degrees Celsius).

Metals are used for electricity transmission, but energy is lost as heat because of electrical resistance.

Moreover, these magnetic moments interact strongly with the electrons in graphene which carry electrical currents, giving rise to a significant extra electrical resistance at low temperature, known as the Kondo effect.

Nope - they actually just have electrical SHIELDS, which we can disrupt and then «shoot with good Russian bullets,» as another resistance guy says.

The reason was because, as I'm sure you know, higher heat = higher electrical resistance.

Also, some of the energy used to overcome inertia and accelerate the vehicle — normally lost when the vehicle is slowed, to aerodynamic forces and rolling resistance as well to the mechanical brakes (as heat)-- may be recaptured as electrical energy if regenerative braking is available (see the discussion of hybrid electric drive trains).

Tested electrical characteristics, such as voltage, resistance and phases in circuits, using voltmeters ohmmeters and phase rotation indicators.

Conducts insulation resistance measurements of electrical cables to determine condition and effects repairs or replacements as required.
