it's been abotu 20 years or so since i've needed to know what was what and why they are called what they are called, so this morning i've got some questions to prepare me for the weekends activities

led's
what are the 2 legs called?
and which one is the positive? the longer one right?

resistors
which way do they flow? towards the single line right?

i know i could google the answers but i'm crap at that and none of the sites i've looked at have given me the answers i'm after

so thanks kind chaps and chapesses for answering
