Hello !
I've got a question about resonance. I know that the circuit is in resonance when XL = XC. So they are reduced to 0.
For example here :
If I have here ZL = ZC two times. Like in series resonance, that it is a short-circuit.
Does it mean that I reduce every ZL and ZC to zero that the only Z here is R ? or just part of it. I mean I know that when ZL = ZC then I have short-circuit. So for example does it mean that C1,L1 and L2 are now as short circuit ? Or is it that all components C1,L1,L2,L3,C2,L4,L5 are short-circuit 2 times and are open circuit 2 times as a whole ?
Also I know that in resonance current is in phase with voltage in voltage source/current source. So I'm not sure.
EDIT:
I'm also not sure here :
Because when there is resonance then this C and L are open circuit ? like in parallel resonance ?
And here :
I know that Im{Y} = 0 and Y is not = 0 so I can as well calculate Im{Z} = 0?
If there wasn't a resistor the Im{Y} and Y = 0 so Im{0} cannot be equal 0 right ?
If I had here resistor not in parallel but in series with voltage source then als Im{Y} = 0 but Y = 0 so Im{Z} is not equal 0.
