ELI5: How does electricity actually transfer energy?
(kbin.social)
Explain it to me like I am 5. Everybody should know what this is about.
Batteries have an insulated separator between the positive and negative sides. They design the battery with a particular maximum voltage in mind, so they engineer it with a separator that is always a higher resistance. Thus the electrons will only be able to make the jump when a circuit with lower resistance is formed.
What would happen if that insulating barrier broke? Would the battery explode or just heat up or something?
