Active voice is what is most commonly used while speaking and writing. In active voice the subject is doing the action and the object is receiving the action, The verb form in active voice depends on the tense the sentence is in.
In passive voice the subject and object switch places, which means that the subject receives the action and the object does the action. The passive voice uses the word by before its object and the past participle form of the verb.
Passive voice is a roundabout way of expressing the same thing as the active voice. We usually use passive voice more in writing than in speaking when our focus is on the action and not on its doer or when we don’t know who the doer of the action is.
