What is the difference between static electricity and electrostatic discharge?

• Electrostatic discharge - charges build on an object. Static Electricity - charges move between objects with different charges.

• Static electricity has no charge. Electrostatic discharge have like charges.

• Static electricity - charges builds on an object. Electrostatic discharge - charges move between objects with different charges.

• They are the same.
