Static electricity is 

• The balance of electrical charge on an object
• The imbalance of electrical charge on an object
• The discharge of electrical charge
• The build up of protons in the nucleus of an atom 

What is the major difference between static electricity and current electricity?

• Current electricity involves a continuous flow of neutrons; 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
