• The voltage periodically changes from positive to negative

• AC is used to deliver electricity to homes and businesses

• AC is the type of electricity that comes from a generator or outlet

  DC direct current

• The electric current flows in one constant direction 

• The voltage is always constant 

• DC is the type of electricity that comes from batteries, solar cells, or from AC/DC converters 

• DC is the preferred type of power for electronic devices 

  ACDC

• AC/DC is an abbreviation for alternating current and direct current
