electric currents

Of course, even if the vessels did produce electric currents, this does not imply that ancient people understood how the objects worked.

records electric currents associated with contractions of the heart.

He was daring; he scaled the Eiffel Tower to find the purest air for a study of electric currents in the atmosphere.

As he travelled, he set up instruments called magnetometers to measure electric currents in the upper atmosphere.

Galvanometer: Instrument for measuring small electric currents by deflection of a moving coil.

By causing it " to wobble and shake, " explains NASA's Hathaway, it induces strong electric currents in the atmosphere and on the ground.

The technique generates a magnetic field on a small part of the skull which creates weak electric currents in the brain.

Evidently electric currents of a peculiar kind had to be produced in order to render the process of nitrogen combustion more efficient.

The corresponding electric currents are used to deflect an electron beam in a cathode-ray tube.

In other words, moving magnets cause changing magnetic fields which try to create electric currents in closed circles of wire.

Steady electric currents flowing along conductors in one direction undergo opposition called electrical resistance, but no reactance.

When electric currents (electrons) are passed through positively-charged gasses (protons and neutron nucleuses) inside bulbs.

attraction for iron; associated with electric currents as well as magnets; characterized by fields of force.

Electric currents persisted only for a moment.

The chief effects of electric currents are the magnetic , heating and chemical effects .

Their vessels contain a diode, a device that allows electric currents to cross it in one direction but not in the opposite direction.

They use tiny electric currents, and have thousands of circuits inside them, put tightly into tiny "chips" .

There are many substances through which electric currents will not pass at all.

The earth's magnetic field is created by electric currents in an ocean of molten iron at its core.

An electric field can thus push these charge-carrying particles along it, creating electric currents.

The electric currents generated by most living cells are extremely smalloften so small that sensitive instruments are needed to record them.

electric fishes Fishes which give out electric currents, e. g. Electrophorus , Torpedo, Mormyrus, based on electric organs.
