Sentences with phrase «electrical resistance through»

The change in electrical resistance through a magnetic field is called magnetoresistance and is very important in technology.

Not exact matches

Thanks to quantum - mechanical effects, below a certain critical temperature some materials become superconducting: electrons flow through them unhindered by the usual electrical resistance.

They found that when a negative electrical potential is applied to skin on various parts of the arm, creating a current, that stretch of skin exhibits a low resistance to a subsequent current flowing through the skin.

Semiconductor gas sensors detect gas through reduced electrical resistance due to gas molecules attached to the surface of crystalline semiconductor materials.

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.

Conventionally such chemical sensors use only the change in the electrical current through the device or a change in the resistance of the device active channel.

Chua's equations suggested that a memristor's electrical resistance, or conductivity, would not be constant, like a lightbulb's, but dynamic, and determined by the history of the current that had flowed through the device.

A film with higher resistance has lower electrical conductivity, meaning that more voltage must be applied to send a signal through it, which further degrades the material.

In particular, injured areas of the body have less electrical resistance and are more susceptible to being damaged through the process.

She runs electrical resistances or sources of heat through the materials she uses, creating delicate and ephemeral physical reactions, revealing all that which in daily life is hidden from view and beyond our comprehension.

Ampere: The unit of measurement of electrical current produced in a circuit by 1 volt acting through a resistance of 1 Ohm.
