Explanation:

• Voice change: Changing the position of subject and object in a sentence is called voice change. The voice can be of two types- active voice and passive voice.
• When the subject is acting upon verb then that voice is called active voice.
• When the subject is acted upon the verb then that voice is called passive voice.
• At the time of changing voice the verb changes according some rules.
• Examples:

1. active voice: Children are playing football.

  passive voice: Football is being played by children.

2. active voice: The teacher has given the homework.

  passive voice: The homework has been given be the teacher.

• If active voice is a simple past tens then the passive voice will be:

       Object + was/were + past participle form of verb + by + subject
