We assume that the resistance is negligible.
Explanation:
We can explain this fact by taking an example of the step up transformer. In step up transformer the voltage level is increased and current level is decreased. It means that current flow though the primary and secondary windings of the transformer. Hence, when current flow through the windings, power losses occur due to the resistance of windings. Power losses in both windings are different due to different number of turns (length difference). So, if we ignore resistance then input power would be equal to output power.
