The new devices, an organic electronic ion pump custom designed for the anatomy of rats, is based on the principle of electrophoresis: the transport of molecules through a fluid or gel under the influence of an electric field. IEEE Spectrum, 8 May 2015 Gel electrophoresis uses an electrical fi...
It turns out that moving charges experience a force in the presence of an external magnetic field. For a given conductor in the presence of a given magnetic field, positive charges moving to the right end up feeling an upward force, and hence would collect on the top end of the conductor...
When electric current passes through an electric element in the circuit, different charge densities occur on both sides of the element leading to electrical potential. So, the electric potential is the work that was done per unit of charge to build the difference in charge densities. What is el...
Air resistance represents a type of external force that affects the rate of acceleration of objects moving in the air. As the amount of air resistance increases, the rate of acceleration decreases.What is Air Resistance? When objects fall from the sky, do larger objects reach the ground before...
The meaning of ELECTROPHORESIS is the movement of suspended particles through a medium (such as paper or gel) under the action of an electromotive force applied to electrodes in contact with the suspension.
If FORCE COPPER is displayed, the combo interface is configured to work as an electrical interface. The preceding command output shows that the combo interface is configured to work as an electrical interface.

where V is the voltage, or electrical potential difference, measured in volts, and R is the electrical resistance to the current flow, measured in ohms (Ω). Think of voltage as a "pulling force" (though this "electromotive force" is not literal...
An inductor (also known as an electrical inductor) is defined as a two-terminal passive electrical element that stores energy in the form of a magnetic field when electric current flows through it. It is also called a coil, chokes, or reactor. An inductor is simply a coil of wire. It ...
The object is the charged particle, and the position is the location of that charged particle within the electric field. Moving a charge against its natural direction in the field requires effort. Once the force is removed, this stored potential energy is converted to kinetic energy. Electrical ...
This interaction can also change the direction of an object. Interaction does not mean, necessarily, contact. A force can be applied to an object through contact (e.g.: push, pull, friction), or it can be contactless (e.g.: magnetic, electrical, magnetic). Figure 2: Pushing is a ...
