Duplicate familiar effect on objects and active spell effects

[x x 806]

The spell duplicate familiar make a copy of the familiar. What happened to objects and spell effects active on the familiar?

-If the familiar has magical objects like wands, scroll or ring of protection does the objects are also duplicate for the duration of the spell?

-If the wizard cast spell like shield on the familiar does the copy also appear with the spell effective ?

Ask your GM.

Most of the time, the game uses the worse choice for you. There isn’t a rule saying as much, but there are other rules demonstrating:
You always round down.
Metamagic spells use the worse level (base or enhanced) for things like spell slot, DC, cost, levels used in ring of spell storing, etc.

If I were your GM, I’d say you get all things duplicated. Charges used on either deplete the base item to preserve WBL.
