whats the difference between vct and vac? I bought a 50 vct 15 amp power supply and when I rectify it its gives me 50 vdc. I thought it would give me the 50 x 1.4 = 70 vdc. Why does it not rectify to 70vdc?
thanks

You need a capacitor on the output of the rectifier, this will store the peak voltage, without this you are getting a ripple DC.
vct is volts centre tapped, i.e. a 50vct transformer has a 50v centre tapped winding that gives 25v + 25v measured from the centre tap.

So for the difference between "VCT" and "VAC":
VAC is alternating current, VDC is direct current.
VCT means "volts centre tapped", which works just like Al descibed. So there really is no relation between VAC and VCT - your power supply can be "centre tapped" no matter if it's AC or DC.
