Spark Gap & Current: Exploring the Impact on Circuits

No need to respond, but be aware that such posts will be deleted.In summary, the conversation discusses the role of a spark gap in increasing the current in a circuit. While it normally acts as an infinite resistance, high voltage can cause ionization and reduce the resistance, allowing for a visible effect and potential sounds. However, no extra current is added and the referenced study has been misrepresented as a potential source of free energy by some sources.

Does a spark gap increase the current in a circuit? My thinking is that the surrounding air is ionized and any "stripped" free electrons would add to the current.

The current that leaves a power source has to be the same as the current that returns to the power source.

A spark gap normally acts as an infinite resistance and stops any current flowing.

However, if the voltage is high enough, ionization occurs and the resistance of the air gap in the circuit is reduced.

The only current flowing is still between the two outputs of the power supply. No extra current is added by the ionization, although the current now has a visible effect and it may produce sounds, giving the impression of a large current flowing.

So what. The study I referenced was done by two professors of physics at Berkeley.

And subsequently misrepresented as being a potential source of free energy by crackpots on that site.

So what? Please re-read the PF rules (see the link at the top of the page). PMM and Free Energy discussions are not permitted here.
 

1. What is a spark gap and how does it impact circuits?

A spark gap is a small gap between two electrodes within a circuit that allows for electrical current to pass through. It creates a small spark or arc when the voltage across it exceeds a certain threshold. This spark can impact circuits by causing disruptions or changes in the flow of electricity.

2. How does the size of the spark gap affect the circuit?

The size of the spark gap can affect the circuit in several ways. A smaller gap may allow for a more consistent flow of electricity, while a larger gap may cause more fluctuations. Additionally, a larger gap may be more prone to creating sparks and arcs, which can damage components in the circuit.

3. What factors can influence the size of a spark gap?

The size of a spark gap can be influenced by several factors, including the voltage and current in the circuit, the distance between the electrodes, and the type of material used for the electrodes. Higher voltages and currents, as well as shorter distances between electrodes, can result in a smaller spark gap.

4. How can a spark gap be used to protect circuits?

A spark gap can be used as a form of protection for circuits by acting as a safety valve. When the voltage in the circuit exceeds a certain threshold, the spark gap will create a spark or arc, diverting excess energy away from the rest of the circuit and preventing damage to components.

5. Are there any downsides to using a spark gap in a circuit?

While a spark gap can provide protection for circuits, there are also downsides to using one. The spark gap can introduce additional resistance into the circuit, which can affect the overall performance and efficiency. Additionally, if not properly designed, a spark gap can cause unintended sparks and arcs, leading to damage or malfunctions in the circuit.
