Question

In a step-up transformer, no. of turns in primary and secondary coils are N1 and N2 then
(A) N1>N2
(B) N>N
(C) N1= N2
(D) N1=0​

Answer 1

Answer:

N2>N1

Explanation:

For steping up means increasing voltage on secondary side only possible when secondary side has more turn

Answer 2

Answer:

(A) N1>N2

Explanation:

as the primary turns in coils contians 100 coils of wire , while the secondary turns in coil has less no. of coils
