02.Electric Potential and Capacitance | NEET Physics
This is a flash card deck for the chapter 'Electric Potential and Capacitance' of Class 12th, based on the latest syllabus for NEET 2024. You can download other chapters by clicking on "The author has shared x other item(s)." below the title of this page.
⚠️TIP: When studying for the first time, focus on learning instead of answering, and when the next time the same card shows up again, then try to answer, so that you know what kind of answer you have to give and understand the question better. Remember, your answer does not need to be theoretically identical to the real answer, answer it in your way and then revise the official answer while checking your own answer. It's Physics so mostly it's just formulas, this deck is best for repetitive revision of formulas, as that's the most important part in physics for NEET, but ofc this is not enough, a good amount of question practice is very important, flashcards can only help you in remembering formulas. I hope these flash cards will help you in your preparations. Best of Luck for your NEET exam, do you best👍🙏.

| Text | Capacitance: Charge stored in a given voltage.Capacitance is independent of charge (Q) and Voltage, it depends on dimensions of conductor and medium filled between plates.Formula → {{c1::
 ::C = ?}}Unit: {{c1::Farad (F) = Coulomb/Volt}}Parallel Plate Capacitor -Formula → {{c1::
 ::C = ?}}{{c1::
 ::Electric Field = ?}}{{c1::
 We can derive this from ΔV = Q/C and ΔV = E×r ::ΔV = ?}}{{c1::
 ::Force = ?}}{{c1::
 ::Work = ?}}Energy stored in a Parallel plate capacitor - {{c1::

| Extra | Equipotential surface (EPS): has constant value of potential at all points on the surface i.e. there is no potential difference b/w any two points on the surface | ΔV = 0Thus work done is also zero, i.e. no work is required to move a test charge on surface.EPS for a point charge → Concentric Spherical surface centered at chargeEPS for uniform electric field → Plane perpendicular to the field Electric field is always perpendicular to equipotential surface.Electric field move from high potential to low potential. |
