Active: Our army defeated the infiltrators.
Passive: The infiltrators were defeated by the army.
· It is mostly used when the importance is to be focussed on the action rather than the initiator of the action.

2. The finite form of the Verb is changed to V3 or past participle.
3. The Subject of the Active sentence becomes the Object in Passive sentence or is completely dropped.
