How Does Electricity Work?
The general concept is taught in grade school and is simple enough that it could be recalled if necessary. A battery here, a potato there, some wires, and eventually, a working lightbulb. Here is a more technical synopsis of how electricity works:
Electricity comes from electron movement. When electrons move together, they produce heat and will flow until their circuit is broken (when a light switch flips off, the current is broken and the electrons stop flowing; whereas, when it flips on, the current is reconnected, allowing the energy flow to continue). These electrons revolve around atom nuclei, which house protons and neutrons. With protons having a positive charge, neutrons having no electric charge, and electrons having a negative charge – these particles balance each other out and work together.
Electrons are attracted to protons, specifically when they are not shelled with other electrons. When a proton pulls electrons out of their orbit, they shift from one atom to another, and this flow of positive-charged electrons creates electricity. The flow can then be directed with conductive materials (like copper wire and subdued with nonconductive materials like sulfur).
