Explanation:
There are two types of voices: active voice and passive voice.
The meaning of the sentence remains the same in both types of voices but the difference occurs in the position of the subject and the object.
In active voice, the subject acts on the object whereas in the passive voice the object is acted upon by the subject.
Another difference that differentiates active voice from the passive voice in the form of the verb used in the sentence.
