Explanation:

In a sentence with an active voice, the subject performs the action which is denoted by the verb. In other words, the subject is the doer of the action. Whereas in a passive voice, the subject is not active but by the verb is acted upon.

Passive voice is the voice used to show an interest in the object or person who experienced the action rather upon the action performer. In passive voice, a subject is an important thing.
