8000 turns

Explanation:

the relation between number of turns of primary and secondary coils and the respective voltages are given as

N1/N2=V1/V2

Where,

•N1 is no. of turns in primary coil

•N2 is no. of turns in secondary coil

•V1 is voltage in primary coil ie, Input voltage

•V2 is voltage in secondary coil ie, Output voltage

from the question we get,

V1=120 V

V2=9600 V

N1=100 turns

N2 = N1 x (V2/V1)

= 100 x (9600/120)

= 100 x 80

= 8000

So, No. of turns in secondary coil = 8000
