The corona discharge can easily lead to an arc flash, by creating a conductive pathway between the lines. This ionization can be enhanced during electrical storms, causing spontaneous arc-flashes and leading to power outages.
Counter-flashing (or cover flashing, cap flashing) is a term used when there are two parallel pieces of flashing employed together [4] such as on a chimney, where the counter-flashing is built into the chimney and overlaps a replaceable piece of base flashing. Strips of lead used for flashing an edge were sometimes called an apron, [5] and the ...
Electric sparks are used in spark plugs in gasoline internal combustion engines to ignite fuel and air mixtures. [6] The electric discharge in a spark plug occurs between an insulated central electrode and a grounded terminal on the base of the plug.
The phase velocity at which electrical signals travel along a transmission line or other cable depends on the construction of the line. Therefore, the wavelength corresponding to a given frequency varies in different types of lines, thus at a given frequency different conductors of the same physical length can have different electrical lengths.

The lead wire is a coated copper wire, a tinned copper wire or another electrically conductive wire used to connect two locations electrically. In electronics, a lead (/ ˈ l iː d /) or pin is an electrical connector consisting of a length of wire or a metal pad (surface-mount technology) that is designed to connect two locations electrically.

Its disadvantages include the cost of refrigeration of the wires to superconducting temperatures (often requiring cryogens such as liquid nitrogen or liquid helium), the danger of the wire quenching (a sudden loss of superconductivity), the inferior mechanical properties of some superconductors, and the cost of wire materials and construction.
