Take a capacitor. You know that it can store charge, right? So, given your thinking process, you might then imagine that the current on one of the terminals can be different from the current at the other terminal of the capacitor. And you might ask, why must it always be that the current goes through the capacitor instead of having current X leaving the left terminal of the …
