What Is Importance & role Of mathematics In Engineering?

This is an infinte long speech. In which specific area do you want to know? And what is the purpose behind asking?

The area in which I emphasis is engineering.

Think of math as a language that describes how a system behaves. That system can be electrical or physical or a combination. It may even describe things that don't exist but are useful for understanding the system. e.g. holes in semiconductors. "Holes" are used instead of electrons because somebody got the sign wrong on the electron.

Conventional current says current (holes) flows from positive to negative. Electrons flow from negative to positive. The world never fixed the formulas. e.g. V=-IR, vs. V=IR Sometimes it's important, like semiconductor physics and electrolosis.

Dear engineering is vast in itself. About which branch of engineering are you talking about?

Hi, Deepika Bansal!

We do help people with homework on this site. But, the keyword here is "help". We don't directly answer homework questions for students here. If we did, how would that be helping them to learn how to come up with the answers themselves?

If you use this site to get help with your homework, please do take some time to come up with and post what you think might be the answers yourself. If you do that, it's likely that you'll have someone very knowledgeable about whatever subject who'll be willing to discuss with you how and why your answers are correct or incorrect.

Please also read the expectations concerning the posting of homework questions that can be found via clicking on the following link.

Whoa, holes exist and have different properties from electrons. They are an important part of the functioning of a semiconductor system. Some semiconductor devices even use the holes as majority carriers instead of electrons (although not many, as electrons often move much faster). However, you're right when you talk about "conventional current".

To the OP. I would challenge you to do anythign in engineering without maths! I struggle to imagine being able to engineer something without any understanding of ratios or number or geometry.
