Ferroresonance or nonlinear resonance is a rare [1] type of resonance in electric circuits which occurs when a circuit containing a nonlinear inductance is fed from a source that has series capacitance, and the circuit is subjected to a disturbance such as opening of a switch. [2]
The Malvern Hills in the United Kingdom, said by Alfred Watkins to have a ley line passing along their ridge. Ley lines (/ l eɪ ˈ l aɪ n z /) are straight alignments drawn between various historic structures, prehistoric sites and prominent landmarks.
Electrical resonance occurs in an electric circuit at a particular resonant frequency when the impedances or admittances of circuit elements cancel each other. In some circuits, this happens when the impedance between the input and output of the circuit is almost zero and the transfer function is close to one.
Watkins' work met with early scepticism from archaeologists, one of whom, O. G. S. Crawford, refused to accept advertisements for The Old Straight Track in the journal Antiquity.

After the FDA has banned red dye No.3, you may be wondering which drinks and candies contain it. Here's the full list—plus, when it'll be removed from shelves.
A Lecher line is a pair of parallel uninsulated wires or rods held a precise distance apart. [9] [1] [10] The separation is not critical but should be a small fraction of the wavelength; it ranges from less than a centimeter to over 10 cm.
