$begingroup$ Beginners can be misled by the idea that electrons "flow". In a simple circuit made from say a battery, a lamp, and a switch, each individual electron would take of the order of one hour to make a complete loop around the circuit. The idea that when you flick a light switch in your house, electrons somehow travel instantly down …
