Discussion Overview

The discussion revolves around the use of induction coils, specifically a 25mm spark gap induction coil, and their output voltage characteristics. Participants explore the feasibility of using this induction coil as a substitute for a neon sign transformer (NST) to power a 6-inch Tesla coil. The conversation includes calculations related to output voltage and the behavior of hydrogen in an electric field.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about how to determine the output voltage of a 25mm spark gap induction coil with a 6V DC input and questions its suitability for powering a Tesla coil.
  • Another participant mentions conducting an experiment on hydrogen behavior in an electric field and suggests that knowing the number of turns in the primary and secondary coils is necessary to calculate the output voltage.
  • A later reply asserts that transformers, induction coils, and Tesla coils are fundamentally different devices, implying that their operational principles may not be interchangeable.
  • One participant shares a graph that estimates the output voltage based on spark length, although the details of this graph are not discussed further.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between induction coils, transformers, and Tesla coils, indicating a lack of consensus on their interchangeability and operational characteristics. The discussion remains unresolved regarding the specific output voltage of the induction coil and its application in the Tesla coil setup.

Contextual Notes

Participants mention the need for specific parameters, such as the number of turns in the coils, to calculate output voltage, but do not provide definitive methods or results. There is also a lack of clarity on the assumptions underlying the calculations and the applicability of the graph shared.

ok, i recently acquired a 25mm spark gap induction coil. the input voltage is 6v dc. how can i know what the output voltage is? also, i want to use this as a substitue in place of a nst to power a 6'' tesla coil. will it work? i mean the basic idea is ot the a high voltage input and the induction coil can do that.
Please post back! Thanks! :smile:

hi,
i'm also using an induction coil to carryout an experiment in studying behaviour of hydrogen in an electric field.but i don't know much abt induction coils...i guess in order to calculate the output you have to know the no: of turns in the primary and the secondary...to determine the output voltage...from E=V/d u can determine the field...
am i correct?

No. Transformers, induction coils and Tesla coils are three different animals.
 
this graph gives a rough estimate of the output depending on the spark length
