If we know that in reality electrons flow from negative to positive, then why is the negative terminal of a battery usually still connected as the ground, and things such as switches usually connect in series to the positive side?
In: Physics
You’re mistaking “ground” with “common”. Most battery powered and DC devices aren’t grounded. Instead, their chassis or major metallic components are connected to one leg of the battery, typically the -. This actually aligns with the correct model of electricity flow.
