A receiving device, like a cell phone or a TV set, detects the energy of an electric field that has been emitted by a source that is far away, where (moving) charges have generated that field. The field has, so to speak, detached itself from the sources and propagated carrying energy with it. When we talk of a vacuum, we mean space empty of ...

where is some volume which encloses all of the charges, and is its bounding surface. Let us assume that is a sphere, centred on the origin, and let us take the limit in which the radius of this sphere goes to infinity. We know that, in general, the electric field at large distances from a bounded charge distribution looks like the field of a point charge, and, therefore, falls off like .

Traditional electric heating uses storage heaters. These store heat inside their core, which is made from a dense heat-retaining material. Usually they heat up overnight, when they can make use of cheaper energy through an off-peak electricity tariff, and gradually release the heat over the following day.

electrostatics, the study of electromagnetic phenomena that occur when there are no moving charges—i.e., after a static equilibrium has been established. Charges reach their equilibrium positions rapidly, because the electric force is extremely strong. The mathematical methods of electrostatics make it possible to calculate the distributions of the electric field and …
