How can I represent electric field lines and Equipotential surfaces using vector Calculus??

Hi ibungo, Your question is a bit vague. What exactly do you mean by 'represent'? Have you calculated the fields and you want a means of presenting or graphing them, or do you want to know how calculate them? Do you have specific examples or any additional information that you could share?

hi jks, What I really want to ask was how to describe electric field and equipotential surfaces in space?? The connections between electric fields and direction lines.

Hmm, I honestly think that you need a textbook. I suggest Engineering Electromagnetic Fields and Waves (either first or second edition) by Carl T.A. Johnk. This was my textbook in college, and I thought highly enough of it to buy the second edition years later (my first edition was falling apart). I suggest buying a used one online at a discounted price. Note that the book will cover significantly more than electric fields and equipotential surfaces.
