How this works
These two tenses split a past moment into foreground and background.
The past continuous - was or were plus the -ing form - describes something already in progress. It sets the scene. "I was cooking." "They were waiting outside." Nothing about it says when it started or finished; it was simply going on.
The past simple is the finished event that happens inside that scene. "The phone rang." "The bus arrived."
Put them together and you get the standard pattern: "I was cooking when the phone rang." The longer action was already running, and the shorter one interrupted it. Reverse the tenses and you reverse the meaning: "I cooked when the phone rang" would mean the call was what made you start.
"When" and "while" point at different halves, which is what makes them worth learning as a pair. "While" almost always introduces the longer action, so it takes the continuous: "While I was cooking, the phone rang." "When" usually introduces the shorter one, so it takes the simple: "I was cooking when the phone rang." Both sentences say exactly the same thing.
Two more uses are worth knowing. The past continuous describes background atmosphere in a story - "It was raining and the streets were empty" - and it describes two things running side by side: "She was writing while he was cooking."
One caution: state verbs do not take the continuous. Know, want, need, believe, understand, like and belong describe states rather than actions, so "I was knowing the answer" is wrong. It is "I knew the answer."
Why this trips up Indian English speakers
The continuous is used more widely in Indian English than in British or American English, and this is the tense where that shows most.
The frequent pattern is the past continuous used for a state: "I was knowing about the meeting", "we were having a doubt", "he was wanting to join". Know, have in the sense of possess, want, need, understand and believe are all state verbs, and English does not put them in any continuous form. The correct versions are "I knew", "we had a doubt" - better still, "we had a question" - and "he wanted".
The second pattern is the past continuous where the past simple belongs, for a completed action: "Yesterday I was going to the office and then I was meeting the client." Both events are finished and both take the past simple: "I went to the office and met the client." The continuous makes it sound as though neither was completed.
The underlying reason is the same as with "I am working here since three years": Hindi uses a progressive construction in places where English requires a simple one, and the mapping is direct enough that it never feels wrong.
The practical test is to ask whether the action was finished. If it was, use the past simple. Keep the continuous for what was still going on when something else happened.

Common questions
What is the difference between past simple and past continuous?
The past simple is a completed action; the past continuous is an action in progress around a point in the past. "I watched the film" means you finished it. "I was watching the film" means it was going on, usually when something else happened.
Should I use when or while?
"While" introduces the longer action and takes the continuous: "While I was cooking, the phone rang." "When" introduces the shorter one and takes the simple: "I was cooking when the phone rang." Both say the same thing; they just start from different halves.
Why is "I was knowing" wrong?
Because "know" is a state verb, and state verbs have no continuous form in English. The same applies to want, need, believe, understand, like, love, hate, own and belong. Say "I knew", "I wanted", "I understood". "Have" is a state verb when it means possess ("I had a car") but an action verb in phrases like "having lunch", where the continuous is fine.
