Answer the question in this post to test your concepts for competitive exams.
I research various interview given by the IITIAN’s and compile a list of Habits/Tips for success in the most coveted examination in the country
Here are the Successful Habits/Tips for clearing IITJEE Examination

We already know about electric field and electric potential. We also know that electrostatic field is completely characterized by vector function E(r). The electric field depicts the force exerted on other electrically charged objects by the electrically charged particle the field is surrounding. Now a question arises why do we need introduction of electric potential when we already have electric field for the description of electric force between charges.
