If there isn't any losses as is the case of ideal transformer. Then as per the answer I want to know, where the remaining power 22.5W is dissipated.

Soln: In the ideal transformer primary is equal to secondary.
Because it has a 1:1 ratio.
So, Input power = Output power.
25watts = 25watts.
Because it has a 1:1 ratio.
So, Input power = Output power.
25watts = 25watts.

In a transformer the ratio of primary to secondary is 9 : 4 if power input is P, what will be the ratio of power output to the power input?

Basically, the ideal transformer ratio is 1:1. So the primary power is 25watts and also secondary power 25 watts.
1 : 1 = 25 : 25.
1 : 1 = 25 : 25.

Simply. The transformer is a machine which do not change the power and the frequency. It is only to change the voltage level

Transformer is a static device which step up od step down the voltage level keeping power constant.
So answer is 25W itself.
So answer is 25W itself.

Turns ratio is given to just confuse the student. The fact is that for an ideal transformer;
Input power = output power.
Input power = output power.

For an ldeal transformer input=ouput since there is no losses in a transformer because there is no moving parts.

Ya its true the transformer only transfers the power, considering losses also efficiency should above 95%.

In transformer constant power so their is no change in input and output power.
i.e. Answer is 25w.
i.e. Answer is 25w.
