   (He is one of many doctors, so we use "a")
   
   
2. He is the doctor who treated me
   (He is the specific doctor who treated me, so we use "the")

Example 2

2. This is the apple which fell on Newton

Types of Articles

They are of 2 types

   They are used to tell about specific person, place or thing
   
   
2. Indefinite Articles
   They are used to tell about something general

Difference

1. I saw a cow 
   The cow was of black colour
   
   (In first line, we are talking about any one cow, not a specific cow.
   So "a" is indefinite article) 
   
   (In second sentence, we are taking about a specific cow of black color.
   So "the" is a definite article)
   
   
2. This is an elephant
   The elephant was very angry
   
   (In first line, we are talking about any one elephant, not a specific elephant.
   So "an" is indefinite article )
   
   (In second sentence, we are taking about a specific elephant who was very angry.
   So "the" is a definite article ) 
   

Summary

1. For specific nouns, we use "the"
