Hi. I've been trying for a whole day now to understand what's the deal with a tank circuit where both the Inductive and the Capacitive reactance are equal. I've learned only that the two cancel each other, the total inductance is infinite and the tank circuit acts like an open circuit. And I've also learned that the two currents overlap, cancel eachother and total current through somewhere in the whole circuit(I don't even know where) is zero. What I want to learn is how is that possible? What happens between the inductor and the capacitor? If no current from the power supply can enter the parallel lc circuit, then how will it be supplied with additional electricity to keep the oscillator going?
