^Parallel plates with different charges
Parallel plates with different charges If the two parallel metal plates X & Y having charge q1 & q2 are placed close to each other. Let the medium between the plates is air or vacuum. then in order to make net electric field in each plate zero, charges redistribute such that inner faces have equal […]
^Capacitance
Capacitance 1. Capacitance of a system is a measure of the its capacity to hold charge for a given potential difference. 2. Capacitance can be defined as 3. Capacitance is defined even if a capacitor is neutral. 4. SI unit of capacitance is Farad (F). 5. 1F = 1 C V – 1 = 9 […]
^Capacitor
Capacitor A capacitor is an arrangement of two conductors (called plates) separated from each other by a dielectric medium & used to trap (or store) electric energy in the form of electric field between its plates.
^Field due to charged conductors
Field due to charged conductors Under electrostatic conditions for a conductor of any shape,
^Field due to sheets
Field due to sheets Using Gauss law we can prove that electric field sheets of charge density σ 1. near a infinite sheet or thick sheet 2. near a finite sheet or thin sheet
^Potential due to concentric spheres
Potential due to concentric spheres Consider two identical concentric spheres of radii R1 & R2 carry charges q1 & q2 respectively as shown in the diagram. Then total potential on A & B will be equal to sum of potentials due to charge on A & B & given by The potential diff. between two […]
^Point charge
Point charge A body of almost no size is called a point body or discrete body i.e. a sphere of radius R → 0 is a point like body. Both field & potential are not defined on a discrete charge, as r → 0 implies E & V → ∞. Outside the point charge field […]
^E & V due to uniformly charged sphere
E & V due to uniformly charged sphere Charge on a insulated sphere of uniform volume charge density r & radius R is , Charge on a spherical insulated shell or a conducting sphere of uniform surface charge density s & radius R is, Q = σ 4 πR2 Using Gauss law we can write
^Factors deciding flux
Factors deciding flux Electric flux depends only upon (a) the number of charges enclosed by Gaussian surface (b) nature of charges enclosed by Gaussian surface (c) nature of the medium. & is independent of (d) size of surface (e) distance between charges inside the surface (f) distribution of charges. Diagram explains that the net electric […]
