Earth Leakage relays & their use in AC system

Hello Ritesh,

It appears that you have entered your entire Homework assignments in these several almost simultaneous questions.

You could also research your subjects via Internet Search Engines.

The reason I say that, is that your questions are ones not well formulated, and look as if your teacher has given you several questions as a Homework assignment.

If you just Copy/Paste answers from here, you are never going to actually remember them, when you are going to need those answers most...in an examination, or later in a Professional situation.

If you do a bit of effort, and actually research the answers (remember to formulate the questions in a more complete way), you are likely to retain the information for life.

If this is not so, please advise here, formulate your questions so they can actually be answered, and I'm sure you should be helped......

Even the same questions twice on the same day????
