Voice (Active & Passive)

Definition: Voice is that form of a verb which tells us whether the subject does something or has something done to it.
For example
Active: Mohan takes coffee. (Subject does something)
Passive: Coffee is taken by Mohan. (Something is done to the subject)

Rules for changing voice:-
(i) Subject is placed in place of object and object is placed in place of subject.
(ii) "By" is used with a noun or a pronoun for showing doer or agent of some work.
(iii) We can change voice of only a transitive verb, i.e., a verb with an object. We cannot change voice of an intransitive verb, i.e., a verb without an object.
