These are represented physically by, for example, two different voltages of an electric current.
Power is supplied by an electric current generated in a pack outside the body.

One such area being addressed is how to distribute a stable electric current across a ship-based grid.
Then he switched on an electric current to heat up the foil instantly to 600 degrees Fahrenheit.
This is similar to cytoscopy, except the probe is used to burn away cancer cells with an electric current.
Cellphones, for instance, rely on chips to detect battery levels and coordinate responses, such as shutting off the electric current when full.
Hydrolysis--running an electric current through water to produce hydrogen--yields fuel that is usually not economically competitive with other forms of energy.
This can be done by heating the gas (a thermal plasma) or passing an electric current through it (a non-thermal plasma).
Michael Faraday discovered in 1831 that an electric current flowing in a wire induces a secondary current in a neighbouring wire.
Many of the tiny metal pieces are cut with a new mechanical process that runs electric current through a hair-thin filament.
He was tracking the electric current from each of his breakers to his various lights, his air conditioner, those types of things.
These two are an industrial pair because they are manufactured in the same process, by passing an electric current through salt water.
It produces an electric current, which the chips use to send out an identifying signal, which the computer recognizes as being me.
Creating a magnetic field using electricity is easy: an electric current flowing in a wire generates a magnetic field around that wire.

It constantly watches the body's heart rhythm and delivers a brief electric current to the heart if necessary to adjust the pacing.
Similarly, moving a magnet creates an electric current in a neighbouring wire.

These run from anode to cathode and thus create an electric current.

Recent work has also demonstrated that at suitably low temperatures they can act as superconductors transmitting an electric current indefinitely, without power loss.
Once cooled, they would be reinvigorated back to their original ionic states by an external electric current, and pumped back into the chip.
Silver is known to kill bacteria, but the addition of an electric current makes the process even more effective, killing up to 98% of bacteria.
Stick the part in acid, run an electric current through it and we can increase the thickness of the layer by a factor of 20-40.
The electric current density possible with such windings is approximately 30 to 100 times greater than the values achievable with copper coils at room temperature.

ABB's best trick is its ability to take electric current of any voltage and frequency, chop it up into tiny bits and reassemble it into the form needed.
These implants convert light into electric current that stimulates local retinal neurons, which then send signals to the brain, meaning no wires are necessary to stimulate the retina.
Dr Benford reckons some of them could have built up an electric current as they moved through the strong magnetic field that pervades the centre of the galaxy.
If you zap purified water with electric current, you can split apart a water molecule into a positively charged hydrogen ion and a negatively charged hydroxide ion (oxygen attached to hydrogen).
The flat panel displays, which make kaleidoscopic colors when jabbed with a finger, contain liquid crystal sandwiched between layers of glass or plastic which becomes opaque with an electric current.
The concept of burning away tumors with electric current dates back a century, but it took modern imaging machines to make through-the-needle tumor-burning accurate enough to be safe and practical.
