HELP measure resonant frequency on induction heating. ?
In this circuit and formula on (GOOGLE).
Please could you help me to know 3 questions:
-How I can measure resonant frequency of this circuit, because it has 2 L and 2 C on this circuit?.
- where I must to put the probes in this circuit for measures frequency?
- If I want to used less power(less heating) I must change L or C or both?
Thank you so much in advance for your time.
