Top best answers to the question «How does electricity know where flow»
The "path of least resistance" is simply the wall that breaks first. In order for electricity to "flow", an electron has to jump from one atom to another, and to do that, it has to push a second electron off of the the atom that it's jumping to.

Electric current is just the flow of electrons in a circuit. For instance, for the light bulb to go on when you press that switch at home, electricity flows from the power stations through the lines, to the lamp, and then finally back to the power source.

Current for the most part does not choose a path, it goes down all paths. Wherever there is a potential difference and an impedance between current can flow. DC wise any resistive path between two points of different potential will cause current t...
We are familiar with two types of electron flow, Direct Current, or DC, and Alternating Current, or AC. Direct Current is the kind of electrical flow we get from batteries and solar cells, when electrons travel in only one direction. On the other hand, AC is the kind of electrical flow we get from a typical electrical outlet in a home.
Electronics students commonly assume that electrical energy flows inside metal wires. Physics students know differently! Electrical energy normally doesn't flow inside of metals. In fact, the joules being sent out by batteries and generators are located in empty space: they take the form of electromagnetic fields surrounding the wires.
How electricity flows The electricity that flows to our homes is generated in power stations. From here, it flows through large transmission lines, which carry it to substations. Finally, distribution lines carry electricity from substations to houses, businesses, and schools like yours!
