How does an electrical post or a wire post didn’t explode when it touch by the water, but whenever you’re in the household and put a water in any outlet it may explode, how does it happen?
In: Engineering
The electrical posts and wires are insulated – covered in plastic or rubber wrapping so that the water doesn’t actually touch the wiring that the electricity is traveling over.
Electrical outlets, though, only have some basic protection (the face plate). Otherwise, it’s just a direct connection to a charged wire – that way when you plug something in, the plug makes contact with the wire and the electricity can freely flow between them. That *also* means though that if you dump water on there… it can cause electricity to spread to *other* areas (like the walls) where it’s not supposed to go, and cause sparks and fire.
