Electric Dipole Notes Plus Two Physics Chapter 1 Electric Charges and Fields

#4 Electric Dipole

An electric dipole is a pair of equal and opposite point charges q and –q, separated by a distance of 2a.

ü From –q to +q is the direction of the dipole

ü The midpoint of locations of –q and +q is called the center of the dipole

ü Dipole moment P = 2aq

ü Total charge of an electric dipole is zero but since the charges are separated by some distance the electric field do not cancel out.

Energy Stored In A Capacitor Class 12 Physics Electrostatic Potential And Capacitance

Energy Stored In A Capacitor We have already studied that capacitors store electrostatic energy in it. Today we will learn how they store energy? and how much energy can be store in a capacitor? As always to find the energy we have to find the work done. So, consider a small positive charge +dQ, work has to be done to transfer this small +dQ to move towards this positive plate(because it's against the electric field). This work is stored as potential energy. Work done W = charge X potential i.e, W =qV Here charge is dQ so we can write dW = dQ V = dQ Q/C ( from equation Q = CV ) integrating on both sides we get This equation consisted to be general equation. By substituting values of Q and C we get other 2 forms of energy stored in capacitor applying Q = CV in equation (1) applying C = Q/V in equation (1) Prev Next You may be Interested In Physics Previous Question Papers With Answers Browse more topics under Electrostatic Potential & Capacitance

Equipotential Surface Class 12 Physics Electrostatic Potential Surfaces And Capacitance

#4. Equipotential Surface Equipotential is the surface which has equal potential at every point on it. Equipotential surface due to a single point charge are concentric spheres having the charge at the center. All the points on a sphere around a point charge have the same distance (radius) so all have same potential. Equipotential surface for a line charge is cylinder Properties of Equipotential Surface Work done for moving a charge on an equipotential surface is zero The potential difference between any two points on equipotential surface is zero Electric Field is always perpendicular to an equipotential surface Equipotential surface for a single point charge are concentric spheres having the charge at the center Two equipotential surfaces can never intersect.
