What are "Tesla Coil" and "Resonant Transformer"?

1. OverviewTesla Coil is a resonant transformer invented by Nikola Tesla in 1891 , used to produce ultra-high voltage, low current, and high frequency electricity. In particular, Tesla coils can produce brilliant arc effects, so thousands of electronics enthusiasts are still making them.Normally, ai

Why should we short-circuit the secondary coil of the transformer when testing the leakage inductanc

When we use a bridge to test the leakage inductance of the transformer, we need to short-circuit the secondary side, and the inductance obtained by testing the primary side is the leakage inductance. Have you ever thought about why you need to short-circuit the secondary side? What is the principle
