Capacitor A device that stores electrical energy in an electric field is known as to be capacitor. It is a passive electronic component with two terminals. It basically consists of two conductors separated by a non-conductive region. This non-conductive region can either be a vacuum or an electrical insulator material known as a dielectric from Coulomb’s law a charge on one conductor will exert a force on the charge carriers within the other conductor, attracting opposite polarity charge and repelling like polarity charges, thus an opposite polarity charge will be induced on the surface of the other conductor. The conductors

Dielectrics Dielectrics are insulating (non-conducting) materials that can produce electric effect without conduction. Movement of free charges is not possible in a dielectric, so they behave differently.When a dielectric material is kept in an electric field, then the external field induces dipole moment. Due to which, net charges on the surface of the dielectric appears.When a dielectric material is kept in an external field, then the induced field will

Proton in an Electric Field Potential difference `(DeltaV)` between two points `A and B` separated by a distance `x`, in a uniform electric field `E` is given by `DeltaV =-Ex`, where `x` is measured parallel to the field lines. If a charge `q_0` moves from A to B, the change in potential energy `(DeltaU)` is given as `DeltaU=q_0 DeltaV`. A proton is released from rest in uniform electric field of magnitude `8.0 xx 10^4 Vm^(-1)` directed along the positive X-axis. The proton undergoes a displacement of 0.50 m in the direction of E.Mass of a proton `= 1.66 xx 10^(-27)
