[tex]Dane:\\n_{p} = 930\\U_{p} = 12 \ V\\U_{w} = 32 \ V\\Szukane:\\n_{w} = ?\\\\\frac{U_{w}}{U_{p}} = \frac{n_{w}}{n_{p}}\\\\U_{p}\cdot n_{w} = U_{w}\cdot n_{p} \ \ /:U_{p}\\\\n_{w} = \frac{U_{w}}{U_{p}}\cdot n_{p}\\\\n_{w} = \frac{32 \ V}{12 \ V}\cdot930\\\\\boxed{n_{w} = 2480}[/tex]
Odpowiedź:
Dane Obliczyć Wzór
n₁ = 930 zw n₂ = ? n₁/n₂ = U₁/U₂
U₁ = 12 V
U₂ = 32 V
Rozwiązanie
n₁/n₂ = U₁/U₂
n₁*U₂ = n₂*U₁
n₂ = n₁*U₂/U₁
n₂ = 930 zw * 32 V / 12 V
n₂ = 2480 zw
Odp. Uzwojenie wtórne ma 2480 zw
