De transformator heeft n1 = 20 windingen en n2 = 100 windingen.
De ingangsimpedantie Z1 is:
a 3 Kohm
b 24 Ohm
c 120 Ohm
d 15 Kohm
n = np/ns n = Up/Us n = Is/Ip n2 = Zp/Zs n2 = Cs/Cp
n = n1 / n2 = 20 / 100 = 1/5 = 0.2
(n*n) = Zp/Zs
Zp= (n2) x Zs>>>>>0.2*0.2*600 = 24 Ohm
n = np/ns n = Up/Us n = Is/Ip n2 = Zp/Zs n2 = Cs/Cp
