fodd bynnag , yr hyn sy'n gyffrous am y datblygiad yn ysgol brynhyfryd yw y bydd y pwer trydanol y bydd ar yr ysgol ei angen yn cael ei gynhyrchu gan gelloedd ffotodrydanol a osodir ar do'r bloc dysgu newydd
however , the exciting part of the development in ysgol brynhyfryd is that the electrical power required by the school will be generated by photoelectric cells placed on the roof of the new teaching block

ar ôl y gyfnewidfa , bwriedir i'r signal deithio ar hyd copr wedi'i droi , sydd ag amrediad cyfyngedig o ganlyniad i ymyrraeth trydanol achlysurol sydd yn diraddio'r signal
after the exchange , the signal is meant to travel along twisted copper , which has a limited range because of stray electrical interference that degrades the signal

trydan ains yw pan fydd eitemau'n cael eu plygio i socedi waliau trydanol. fel rheol mae angen mwy o egni ar y rhain gan y byddai batris yn rhedeg allan yn gyflym pe byddent yn cael eu defnyddio. defnyddir trydan yn aml gydag offer mwy sydd fel arfer yn aros mewn un lle. mae dyfeisiau a weithredir gan fatri yn tueddu i fod yn llai ac yn fwy cludadwy.
ains electricity is when items are plugged into electrical wall sockets. these normally need a higher amount of energy as batteries would quickly run out if they were used. electricity is often used with larger appliances that normally stay in one place. battery operated devices tend to be smaller and more portable.
