Re: [TCML] Low power coil means physically small coil ?



Hello,

Thank you for your answers.

Now about the complex questions, i expect the factors of influence to be
numerous and interlinked, but could i have some elements of answer or
literature about them ? I'm really interested in the deep theory of Tesla
coils.

With kind regards,

Christopher Gerekos
