What is the resulting amperage from a Leyden jar discharge?

Click For Summary
SUMMARY

The discussion centers on calculating the resulting amperage from a Leyden jar discharge. A participant shares their Matchcad calculations but expresses concern over the extremely high amperage results. It is established that discharging a near-ideal capacitor can produce a momentary pulse of current approaching infinite amperes, while non-ideal components will reduce this amplitude and extend the discharge duration. Accurate calculations require a clear understanding of the relationship between charge and resulting current.

PREREQUISITES
  • Understanding of Leyden jar principles and operation
  • Familiarity with electrical current calculations
  • Knowledge of capacitor discharge behavior
  • Experience with Matchcad software for simulations
NEXT STEPS
  • Research the relationship between charge (Coulombs) and current (Amperes) in capacitor discharges
  • Study the effects of non-ideal components on current amplitude and duration
  • Learn about the mathematical modeling of capacitor discharges using Matchcad
  • Explore practical experiments with Leyden jars to observe discharge characteristics
USEFUL FOR

Electronics enthusiasts, physics students, and engineers interested in capacitor behavior and current calculations will benefit from this discussion.

I need to figure out how to correctly calculate the Current being created from a leyden jar I have. I am attaching a print screen of a matchcad calculation that shows what I have done. However, I am calculating extremely high amperage. I believe my calculation is correct down to my charge, but I do not know how to correctly relate my charge to the resulting amperage. Have a look! any suggestions please!

If you discharge a near-ideal capacitor with an almost perfect conductor, there will be a momentary pulse of current approaching infinite amperes. Non-ideal components reduce the amplitude, and extend the duration.
