in start write a formula and then explain       * Active & Passive Voice with example

Sure, let's start with the formula:

Active Voice: Subject + Verb + Object Passive Voice: Object + Auxiliary Verb + Past Participle + by + Subject

Now, let's explain:

1. Active Voice: In an active voice sentence, the subject performs the action. It's a more direct and preferred style of writing in most cases. For example, "John ate an apple." Here, John (subject) is performing the action of eating.

2. Passive Voice: In a passive voice sentence, the subject is acted upon by the verb. It's used when the focus is on the action, or when the doer is unknown or irrelevant. For example, "An apple was eaten by John." Here, the focus is on the action of the apple being eaten, not on John.

Remember, the meaning of the sentence does not change, just the focus shifts from the subject to the action or object.
