Hurry i have 15 minutes describe the proccess which mendeleev developed the 1 periodic table of the elements

In 1869, just five years after John Newlands put forward his law of octaves, a Russian chemist called Dmitri Mendeleev published a periodic table. Mendeleev also arranged the elements known at the time in order of relative atomic mass, but he did some other things that made his table much more successful.  

i hope this helps in some way!

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
