Current “flows in a closed path or circle. Breaking/opening the path anywhere along its length will stop the current. The common mode choke accomplishes this. The common mode voltage is still coupled through the stray capacitance/resistance, but there is no current because the common mode choke opened the circuit . | |

| Feb 26, 2023 at 14:34 | comment | added | user319836 | What current are you referring to? | |
| Feb 26, 2023 at 9:28 | comment | added | Jess | Also, I agree with you on the fact that the common choke isolates unbalanced circuitry from balanced circuits by increasing the impedance path for common mode signal. But the current still have to pass somewhere and we go back to the schematic that I have drawn with the hidden capacitors ? | |
| Feb 26, 2023 at 9:23 | comment | added | Jess | Thank you for your answer. I missunderstand why the tighter the twist, the better is the balance to ground. If I have a really tigh twisted pair of wire, but a large loop between those wires and the ground, I will still have a possible noise that can couple whatever if the pair is well tighted or not ? | |
