What is the major difference between static electricity and current electricity?
Current electricity involves a continuous flow of elecrons; static electricity is a sudden transfer of protons
Current electricity can be deadly; static electricity is almost always safe
In current electricity, there's a single transfer of electrons; in static electricity, there's a steady flow of electrons
Current electricity involves a flow of electrons; static electricity involves a single transfer of electrons
