Do Electrons in a series circuit all follow the same path?

Answer 1

No, they cant take multiple paths because for one component of the circuit to operate it can bypass the other components to power that one. It does not require all components to be on(like a series circuit) for just one component to operate.

Answer 2

Yes and No.

Yes, all electrons in a series circuit, at the global level, follow the same path, because there is only one path, and, by Kirchoff's Current Law, all the current entering a node is accounted for in the current leaving the node, which means that the current at every point in a series circuit is the same.

No, even in a series circuit, at the atomic level, there are multiple paths, because there are multiple atoms for the electrons to "choose from". Electrons jump from atom to atom based on relative potential differences. Even a series circuit, at the atomic level, is a nearly infinite number of parallel circuits.
