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 ...
Dual Resonant Solid State Tesla Coil (DRSSTC): The circuit is similar to the double tuned spark excited circuit, except in place of the AC supply transformer (T) in the primary circuit a DC power supply charges the capacitor, and in place of the spark gap semiconductor switches complete the circuit between the capacitor and the primary coil.
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 ...
This voltage is often sufficient to cause an electric spark, to jump across an air gap (G) separating the secondary's output terminals. For this reason, induction coils were called spark coils. An induction coil is traditionally characterised by the length of spark it can produce; a '4 inch' (10 cm) induction coil could produce a 4 inch spark.
It requires mechanical power to turn the disks against the electric field, and it is this energy that the machine converts into the electric power of the spark. The steady-state output of the Wimshurst machine is a direct (non-alternating) current that is proportional to the area covered by the metal sector, the rotation speed, and a ...
The electrode and workpiece are connected to a suitable power supply. The power supply generates an electrical potential between the two parts. As the electrode approaches the workpiece, dielectric breakdown occurs in the fluid, forming a plasma channel, [16] [23] [24] [25] and a small spark jumps.
