 This is completely OT but dont know where else to ask. I need to buy a
 transformer with a 12V 8A secondary and looking at the Newark catalog, I
 have transformers that have "C.T." written next to the secondary voltage.
 In the footnotes it says that C.T. stands for Center Top. Anyone knows what
 Centor Top means? And now that I have already wasted bandwidth, anyone
 knows of a cheap source for transformers?

Hi Shahid,

If your docs say Center Top then its a typo.  The correct phrase should be
"Center Tap".
This is a tap (or a wire attached to) the center of the seconday winding of
the transformer.  If a transformer is labeled 25VCT, then you will get 25
volts between the outer two leads and 12.5 volts between the center tap and
either of the outer leads.  This is conveniant to get multiple voltages or can
be used in two diode full wave rectifiers to produce DC from the AC that comes
out of the transformer.

Hope this helps
