Case study question of Physics – Electrostatic potential and capacitance Case study 3:- A dielectric slab is a substance which does not allow the flow of charges through it but permits them to exert electrostatic forces on one another. When a dielectric slab is placed between the plates, the field polarises the dielectric. This induce … Read more
Case study question of Physics – Electrostatic potential and capacitance Case study 2:- This energy possessed by a system of charges by virtue of their positions. When two like charges lie infinite distance apart, their potential energy is zero because no work has to be done in moving one charge at infinite distance from the … Read more
Case study 1:- The potential at any observation point P of a static electric field is defined as the work done by the external agent (or negative of work done by electrostatic field) in slowly bringing a unit positive point charge from infinity to the observation point. Figure shows the potential variation along the line … Read more
Case study question of Physics – Electrostatic potential and capacitance Case study 4:- Potential difference (ΔV) between two points A and B separated by a distance x in a uniform electric field E is given by ΔV = -Ex, where, x is measured parallel to the field lines. If a charge moves from P to … Read more
