what will be the ripple voltage if ripple factor is 3% and output Voltage is 18Vdc in center tapped full wave rectifier?
Can you please tell me the formula?

Input Voltage though converted to dc output yet has 3% ac component
You are definitely on the right track. Ripple voltage has a pretty specific meaning and what you've described MIGHT mean that, but more reasonably could mean a couple of other things.

So I'd suggest doing a bit of searching on ripple voltage and see if you can't refine that a bit.
