- OIL RIG: Oxidation Is Losing; Reduction Is Gaining (electrons)
- AN OX (ANode is where OXidation occurs)
 RED CAT (REDuction occurs at the CAThode)
- Electrolytic cell — electrical energy is used to bring about a nonspontaneous electrical
 change. Anode is (+) electrode; cathode is (−) electrode.
- Voltaic (chemical) cell — electrical energy is produced by a spontaneous redox reaction.
 Anode is (−) terminal; cathode is (+) terminal.
