Question

A Step-Up Transformer which has
110/220 turns.What would happen if
we replace it with 10/20 turns?
(because Turns ratio would be
same in both cases)

Answer 1

If we replace it with 10/20 turns, the induced emf will decrease

Explanation:

Given:

A step-up transformer has 110/220 turns

To find out:

What will happen is it is replaced by 10/20 turns

Solution:

We know that in a transformer, flux is directly proportional to number of turns N

Thus,

$\Phi\propto N$

Therefore, if the number of turns are more then flux will be more

Also the EMF is directly proportional to the flux

Thus,

$\text{EMF}\propto \Phi$

Hence if flux is increasing, the EMF will also increase and vice versa

Therefore, the Step-Up transformer with less number of turns will have less induced emf

Hope this answer is helpful.
