Electricity resistance creates a lower threshold of power that has to be met before it starts flowing. If the force of the electricity isn’t strong enough to start any movement, then the electrons just don’t move. It is the moving electrons interacting with what they are moving through that causes the fire-starting, plastic-melting heat.
This is especially true in a system like a house, where there is always a different path of least resistance somewhere else so the outlet is never the only resistance holding back the electricity.
