When two or more identical capacitors are connected in series across a potential difference?

When two or more identical capacitors (or resistors) are connected
in series across a potential difference, the potential difference divides
equally among them.

For example, if you have nine identical capacitors (or resistors) all
connected end-to-end like elephants in a circus parade, and you
connect the string to a source of 117 volts (either AC or DC), then
you will measure

(117v / 9)  =  13 volts

across each unit in the string.

I'm not sure what your asking buddy.. but i know that you can weld two peices of steel by pure force and pressure.
