NEET 2024, Physics Q15: Faraday’s Law of Induction

NEET2024Physics

Q.

In an ideal transformer, the turns ratio is $\frac{N _{p}}{N _{s}} = \frac{1}{2}$ . The ratio $V_{s} : V_{p}$ is equal to (the symbols carry their usual meaning):

A
1 : 1
B
1 : 4
C
1 : 2
D
2 : 1

Solution

For an ideal transformer $\frac{V _{s}}{V _{p}} = \frac{N _{s}}{N _{p}} = 2$ .

$∴ V_{s} : V_{p} = 2 : 1$ .
