... Definition: A field is conservative if the work done in moving between any two points is independent of the path taken. E is conservative because ∆V is independent of the path. Proof: Consider the field due to a point charge Q. If we can prove it for this we can argue from the principle of superposi ...

... dE/dx of electric field over depth x is proportional to the density of dopant in the depleted substrate, and, hence, is constant. This means that if we plot E as a function of depth, the plot is a stright line. Since voltage is an integral of electric field, V0 is an area under the triangle and is e ...

But for non steady currents such as this one, the concept of current enclosed by a loop is ill-defined since it depends on what surface you use. In fact Ampere's ...

Electroactive polymers

Electroactive polymers, or EAPs, are polymers that exhibit a change in size or shape when stimulated by an electric field. The most common applications of this type of material are in actuators and sensors. A typical characteristic property of an EAP is that they will undergo a large amount of deformation while sustaining large forces.The majority of historic actuators are made of ceramic piezoelectric materials. While these materials are able to withstand large forces, they commonly will only deform a fraction of a percent. In the late 1990s, it has been demonstrated that some EAPs can exhibit up to a 380% strain, which is much more than any ceramic actuator. One of the most common applications for EAPs is in the field of robotics in the development of artificial muscles; thus, an electroactive polymer is often referred to as an artificial muscle.
