A small demonstration Marx generator (tower on the right). It is a ten stage generator. The main discharge is on the left. The nine smaller sparks that can be seen in the image are the spark gaps that connect the charged capacitors in series. A Marx generator is an electrical circuit first described by Erwin Otto Marx in 1924. [1]
A spark on a spark plug Lightning is a natural example of an electric spark. An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized, electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures.
Small spark gaps are very common in telephone switchboards, as the long phone cables are very susceptible to induced surges from lightning strikes. Larger spark gaps are used to protect power lines. Spark gaps are sometimes implemented on Printed Circuit Boards in electronics products using two closely spaced exposed PCB traces. This is an ...
Tesla coil circuits were used commercially in spark-gap radio transmitters for wireless telegraphy until the 1920s, [1] [4] and in medical equipment such as electrotherapy and violet ray devices. Today, their main usage is for entertainment and educational displays, although small coils are still used as leak detectors for high-vacuum systems ...
One or more resonant circuits (tuned circuits or tank circuits) which create radio frequency electrical oscillations when excited by the spark. A resonant circuit consists of a capacitor (in early days a type called a Leyden jar ) which stores high-voltage electricity from the transformer, and a coil of wire called an inductor or tuning coil ...
A typical low-tension coil (reproduction) used in the ignition system of an ignitor-fired engine. A low-tension coil is an electrical device used to create a spark across the points of an ignitor on early-1900s gasoline engines, generally flywheel engines, hit-and-miss engines, and other engines of that era.
That foundation can make a slow-burn stronger than a spontaneous spark because the oxytocin whirlwind of a love-at-first-sight romance “isn’t always stamina for a [long-term] relationship ...
A trigatron is a type of triggerable spark gap switch designed for high current and high voltage (usually 10–100 kV and 20–100 kA, though devices in the mega-ampere range exist as well). It has very simple construction and in many cases is the lowest cost high energy switching option.
