There are TWO TYPES of Voices in English language. 

They are: 

1.Active voice. 

2. Passive voice. 

When we express an idea giving importance to the doer, the sentence is written in the active form. 
That means that the ‘doer of the action’ is active. 

• He wrote a letter. 

When we express an idea giving importance to the action rather than to the doer, the sentence is written in the passive form. 
That means that the ‘doer of the action’ is not active but passive. 

• A letter was written by him. 

In passive form, the verb will be in past participle form. 

“Write" is Present tense form of the verb. 

“Wrote" is past tense form of the verb 

“Written" is past participle form of the verb 

Since “a letter" was singular form, it is followed by singular-past tense verb “was". 

Let us see one by one:
