electric potential

n.
The work per unit of charge required to move a charge from a reference point to a specified point, measured in joules per coulomb or volts. The static electric field is the negative of the gradient of the electric potential.

electric potential

n
(General Physics)
a. the work required to transfer a unit positive electric charge from an infinite distance to a given point against an electric field
b. the potential difference between the point and some other reference point. Symbol: V or φ Sometimes shortened to: potential

It can be seen from the figures that the positive piezoelectric potential causes the increasing of the vibration amplitude, the negative electric potential causes the decreasing of the vibration amplitude, and it is feasible to attenuate the vibration of the underwater structure by applying a suitable piezoelectric potential.
Without electric potential, the concentrated peeling stress is 8.3 MPa.
Second, modifying the linear Maxwell theory to the nonlinear electrodynamics theory can eliminate the problem of divergency in electromagnetic field and leads to finite self-energy and finite electric potential at the origin.
Exploiting the fact that j is divergence-free, one can derive from (1) a Poisson equation for the electric potential:
where [n.sub.0] denotes the average number of positive or negative ions in the buffer, z is the valance, e is the electron charge, T is the absolute temperature, [psi] is the electric potential, and [k.sub.B] is the Boltzmann constant.
While a large number of processes over the years have involved surgically implanted electrodes that apply electric potential directly to the spine, there is still no precise understanding of its mode of action--these signals somehow interfere with the human pain signaling circuitry.
An electric field is characterized by an electric potential difference divided by distance or more commonly in standard units "volts per meter." It is a difficult measurement to make because there is not much current involved.
Results for the electric potential and current density in various sections of the model are presented.
To the Editor: The cover reference "Tapping Water Power" on your February 2013 issue led me to the article "Waves, Currents, and Electric Potential" on page 40.
This surge in electric potential might tip off another passing bee that the flower had just lost nectar to a different visitor, a change that scent or color could not reveal, Robert says.
In Figure 2 and Figure 3, [E.sub.s] is the electric potential of system power, [X.sub.s] is the reactance of system power.
Fairport, NY, January 05, 2013 --(PR.com)-- A new, low cost, contactless gesture-recognition technology called imPart[TM] will be shown at CES 2013 in Las Vegas January 8-11 which uses Plessey Semiconductor's award-winning EPIC[TM] electric potential sensors.
