Question

How are static electricity and current electricity alike and different?

Answer 1

-- Static electricity and electric current are both results of the behavior of huge
numbers of electrons. 

-- When electrons bunch up and stay in one place, you have static electricity.

-- When electrons flow from one place to another, that's electric current.

Answer 2

Alike - Both have charge ; that is, both possess electrons.

Difference - Static electricity is stable; it does not flow. Current is not stable and flows in the medium.
