What exactly does the capacitor do in a Tesla coil?

Click For Summary
SUMMARY

The capacitor in a Tesla coil serves a crucial role in the primary circuit by storing electric energy during the charge-up cycle. This energy is then released to create a resonant tank circuit, which is essential for the operation of the Tesla coil. The discussion emphasizes the importance of the capacitor's function in energy storage and release, directly impacting the efficiency and performance of the coil.

PREREQUISITES

In all tutorials I have read on tesla coils, they have said to use a capacitor spark-gap configuration, to create a tank circuit. I want to know exactly what this means, and what is its purpose. I am not going to build a Tesla coil, I am nearly just interested in the science of it.

The capacitor on the primary side? It stores electric energy during the charge-up cycle of Tesla coil operation.

Yes, on the primary side, and that's it?
