Very very simple question about bridge rectifiers

In a bridge rectifier made of four diodes, which side is the supply (+) and
ground (-)? I'm assuming the supply (+) is on the side that both cathode
ends connect to, correct?

Thanks,
Harry

Loads and loads and loads of information available on the net that
would have answered your question in less than a minute. I googled
"bridge rectifier circuit symbol" to get an explanatory diagram like
this one;

or simply "bridge rectifier" to get a detailed tutorial from tpub.com
(excellent technical resource!)

Your terminology threw me at first. The input is AC so it has no
polarity. The pulsating DC output you refer to as the "supply" does
exhibit polarity as you indicate.

Er... just check the current flow directions on his first blue diagram
and in the explanation. Looks distinctly reversed to me!
