Electric shock — Physiological reaction of a biological organism to the passage of electric current through its body. Ferranti effect — A rise in the amplitude of the AC voltage at the receiving end of a transmission line , compared with the sending-end voltage, due to the capacitance between the conductors, when the receiving end is open ...
Geometrical arrangement for two plane wave interference Interference fringes in overlapping plane waves. A simple form of interference pattern is obtained if two plane waves of the same frequency intersect at an angle. One wave is travelling horizontally, and the other is travelling downwards at an angle θ to the first wave.
A time-domain reflectometer; an instrument used to locate the position of faults on lines from the time taken for a reflected wave to return from the discontinuity.. A signal travelling along an electrical transmission line will be partly, or wholly, reflected back in the opposite direction when the travelling signal encounters a discontinuity in the characteristic impedance of the line, or if ...
The same phenomenon would seem to have two different descriptions depending on the frame of reference of the observer. This problem, along with the Fizeau experiment , the aberration of light , and more indirectly the negative aether drift tests such as the Michelson–Morley experiment , formed the basis of Einstein's development of the theory ...
Electrical phenomena are commonplace and unusual events that can be observed which illuminate the principles of the physics of electricity and are explained by them. Electrical phenomena are a somewhat arbitrary subset of phenomena of electromagnetism in general.
It is analogous to the Stark effect, the splitting of a spectral line into several components in the presence of an electric field. Also similar to the Stark effect, transitions between different components have, in general, different intensities, with some being entirely forbidden (in the dipole approximation), as governed by the selection rules.
Pick any one of the more than 50 ships or 20 planes that have disappeared in the Bermuda Triangle in the last century. Each one has a story without an ending, leading to a litany of conspiracy ...
Even if all of the audio and video equipment in, for example, a home theatre system is plugged into the same power outlet, and thus all share the same ground, the coaxial cable entering the TV may be grounded by the cable company to a different point than that of the house's electrical ground creating a ground loop, and causing undesirable ...
