What I did:
I looked up an article to find out the meanings and differences of active and passive voice.
What I learnt:
I learnt that while active voice is used when a subject does an action that acts upon another object, passive voice is used when an object is acted upon by another object. Also, certain sentences which do not have a direct object cannot be changed from active to passive voices. Active voices flow smoother and can be understood easier, however, passive voices are better when the one doing the action is unknown, or if emphasizing the object being acted upon is needed.
