Sparks and Allied Phenomena
Horizontal lines randomly arranged on a television screen may be caused by sparking in a malfunctioning electrical device. Electric railways can also be a strong source of this type of interference.
Other possible sources of such interference include:
- Thermostats, fridges, freezers, fish tank heaters, central heating systems
- These can create sparks as they turn on or off; as they age they can become worse. In some rare cases they can create non-stop interference through sparking.
- Electric motors
- Motors which have a commutator can suffer from sparking at the brushes.
- Ignition systems on cars and motorbikes.

Famous quotes containing the words sparks and, sparks, allied and/or phenomena:
“The genius of reading and of gardening are antagonistic, like resinous and vitreous electricity. One is concentrative in sparks and shocks: the other is diffuse strength; so that each disqualifies its workman for the other’s duties.”
—Ralph Waldo Emerson (1803–1882)
“The genius of reading and of gardening are antagonistic, like resinous and vitreous electricity. One is concentrative in sparks and shocks: the other is diffuse strength; so that each disqualifies its workman for the other’s duties.”
—Ralph Waldo Emerson (1803–1882)
“Can love be in aught allied to dissipation? Let us love by refusing, not accepting one another. Love and lust are far asunder. The one is good, the other bad.”
—Henry David Thoreau (1817–1862)
“It is impossible to dissociate language from science or science from language, because every natural science always involves three things: the sequence of phenomena on which the science is based; the abstract concepts which call these phenomena to mind; and the words in which the concepts are expressed. To call forth a concept, a word is needed; to portray a phenomenon, a concept is needed. All three mirror one and the same reality.”
—Antoine Lavoisier (1743–1794)
