Three Prong Plugs
The Main Idea
Why do outlets need that third prong? Grounded electricity explained without any confusing math or equations.
A Mathematical Model
Don't be silly, this is a page for dummies. Let's not bother with equations, as the real world is more complex than theory as it is.
A Computational Model
Below is a circuit diagram of the standard American three-prong outlet. The third prong provides a common zero voltage at either side of the green neutral connection, and removes the possibly fatal consequences of the neutral line resistance from the electric circuit. [[1]]
