electro-, electr-, electri-

(Greek > Latin: electric, electricity; from amber, resembling amber, generated from amber which when rubbed vigorously [as by friction], produced the effect of static electricity)

Electronics in our lives consists of numerous tools

Equipment which we use everyday relies on electronics to function including calculators, car controls, cameras, washing machines, medical scanners, mobile telephones, radar systems, computers; as well as many other applications or devices which are listed in this unit.

unipolar electrocardiogram
1. An electrocardiogram taken with the exploring electrode placed on the chest over the heart or upon a single limb, the indifferent ("zero" potential) electrode being the central terminal.
2. An electrocardiogram that shows the potential detected by a single electrode.

In practice, this is obtained by using an exploring electrode and a second electrode; such as, a central terminal that is assumed to have zero potential.

ureteral electromyography
The recordings of the various electrical currents during contractions of the ureter.
vacuum-tube electrometer
An electrometer is a device that uses, as an amplifier, a vacuum tube having a very high input impedance which is the measure of the opposition that an electrical circuit presents to the passage of an electric current when a voltage is applied.
valence electron
One or more of the electrons in an atom's outermost, incomplete electron shell.

Such electrons are exchanged or shared in chemical reactions.

zeta potential, electrokinetic potential, bioelectric potential
1. A potential gradient that arises across the interface between the boundary liquid layer in contact with a solid and the movable diffuse layer in the body of the liquid.
2. Electrokinetic potential refers to the potential developed across any interface separating two phases as a result of the accumulation of electrons in one phase and the loss of electrons in the other.
3. Bioelectric potential refers to the difference of electric potential between the inside and the outside of a cell.
4. The ratio of the zetacrit to the hematocrit, used as an indicator of the red blood cell sedimentation rate.
5. The potential developed across any interface separating two phases as a result of the accumulation of electrons in one phase and the loss of electrons in the other direction.
zone electrophoresis
The electrophoretic separation of migrating molecules in a conducting medium which is immobilized onto an inert supporting medium such as paper, cellulose acetate, or agar gel.

Zone electrophoresis allows more manipulation of the separated proteins than moving-boundary electrophoresis.
