Active Voice- Active voice is a grammatical structure in which the subject of the sentence performs the action expressed by the verb.

Passive Voice- Passive voice refers to a grammatical construction where the subject of a sentence undergoes an action rather than performing it. In passive voice sentences, the emphasis is on the recipient or object of the action.
Conversion rule:
is, am, are + Subject + verb + ing + object? -> <- auxiliary verb (is, am, are) + Object + being + past participle + by + subject?
