Each Councillor is elected to represent a specific area (Electoral Ward) and normally serves for a period of four years after which time they then have to stand for re-election.
Etholir pob Cynghorydd i gynrychioli ardal benodol (Ward Etholiadol) ac fel arfer bydd yn gwasanaethu am gyfnod o bedair blynedd (pryd bydd yn rhaid iddynt sefyll eto os ydynt am gael eu hail-ethol).
