Consequently, why is current electricity used more by man than static?
Whereas, the current electricity develops because of flow of charges. The static electricity develops because of the movement of negative charges from one object to another. The current electricity is because of the movement of electrons in the atoms of the conductor.
Beside above, why is current electricity useful? Electricity is used to operate your cell phone, power trains and ships, run your refrigerator, and power motors in machines like food processors. Electric energy must be changed to other forms of energy such as heat, light or mechanical in order to be useful.
In this way, how is static electricity different from current electricity?
1. Static electricity is caused by the build up of electrical charges on the surface of objects, while current electricity is a phenomenon from the flow of electrons along a conductor.
How much current does static electricity have?
The average socket you'd see in a home puts out somewhere between 10 and 20 Amps to power your electronic devices. The typical static electricity you'd encounter when touching a doorknob contains a current that it negligible. That's why the 1,000 volts caused by the pop when you touch a doorknob doesn't kill you.
