Yes, their wands are related because they both contain a feather from the same phoenix (Fawkes). They are "twin" wands, and therefore cannot go one against the other.
Voldemort used Lucius' wand while chasing Harry on his 17th birthday.
harry and voldemort both have a huge face-to-face battle while millions of ppl so witches/wizards watching around them and duelling other death eaters... btw harry wins and kills voldemort at the end.. by getting the elder wand and shooting a stunning spell out of his wand and the elder wand.... the good wins, the evil looses. and tht was destined to happen and always will happen forever and forever- Prit Parikh quote..
The reader doesn't know.
The final spell that Harry Potter uses in the books + movies is "Expelliarmus". Though he does catch Voldemorts wand and use Voldemorts own spell against him, but Harry doesn't actually cast that one, Voldemort does.
Yes he does posses it but never is the owner of it. It is confusing but I will explain from when Dumbledore has it. OK Dumbledore has the wand and is it's master. Draco disarms him and because of it unknowingly becomes the owner of the wand. Voldemort steals the wand from Dumbledore's grave but because he is not the true owner it does not work for him. Voldemort believes because Snape killed Dumbledore he is the owner of the wand so kills Snape. Harry wrestles Draco's wand from him and physically overpowers him becoming the new owner of the Elder wand (due to Draco's defeat) Then Harry and Voldemort face off, Voldemort with the Elder wand that Harry masters so Harry wins. So Voldemort Physically has the wand but never masters it so it works as normally as any other wand for him.
