Post by okI am trying to assemble a DIY 1 watt amp kit set. It comes with some
capacitors that each one has one long leg and one short leg. Would somebody
please tell me which leg is positive? Thank you in advance.
Assuming that they're electrolytics. (Shaped like a tin can, either
two legs from one end, or a leg at each end.)
The long leg is the postive (+) lead. There will also usually be a
very wide & visible black stripe running along one side of the
capacitor which will indicate the positive lead, or will have a symbol
"(-)" & an arrow ">" pointing towards the negative lead.
As someone has already mentioned, bipolar electros can be placed
either way around, *but* make sure that they *are* bipolar cap's
before soldering them in, because a normal (polarised) electro will go
*BANG!* if you put it in backwards & power it up! Bipolar electros
will normally be clearly marked with the word "bipolar" on the label.
