Pomoć oko zadatka (transformator)

Napravi izračun transformatora uz podatke

 

J=3.6 A/mm na kvadrat

P=320 W

U2=2*15V

 

Ja sam izračunao I2,A,a,Acu2,d2... molio bi vas da ostale vrijednosti izračunate

  J=? Misliš na ρ (ro)?

J=  gustoća materijala

 

znači

J=I1/Acu1

krivo mislis, gustoca se mjeri u kg/m kubnom.

ovo je koliko vidim mm/m kvadratnom

Ovdje se ne radi o gustoći materijala, nego o otpornosti.

 

ρ = (R * A)/ l

 

otpornost = (otpor   * presjek) / duljina žice
