Frequently Asked Questions
Q1: What is coulomb’s law?
A1: Coulomb’s Law states that the force between two point charges Q1 and Q2 is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Q2: What is Gauss law?
A2: The electric flux passing through any closed surface is equal to the total charge enclosed by that surface.
Condition for Gauss law
- Surface may be irregular but should be sufficiently large so as to enclose the entire surface
- The surface must be enclosed
- At each point of the surface D (total charge enclosed by the surface) is either normal or tangential to the surface
- D is constant over the surface at which it is normal
Q3: What is equi potential surface?
A3: An imaginary surface in an electrical field of a given charge distribution in which all the point on the surface are at the same electric potential.
Q4: What are the properties of dielectric material?
A4: Properties of dielectric material are,
- the dielectrics do not contain any free charges but contain bound charges
- The electric field outside and inside the dielectrics gets modified due to the induced electric dipoles
- Due to the polarization, the dielectrics can store the energy
- Due to the polarization the flow density of the dielectrics increased by the amount of equivalent to polarization.
Q5: What is boundary conditions and its types?
A5: The conditions existing at the boundary of the two medium when field passes from one medium to other is called boundary conditions. Depending upon the nature of the medium, it can be classified into three types
- Boundary between dielectric and dielectric
- Boundary between conductor and dielectric
- Boundary between conductor and free space
To determine the boundary conditions, maxwell’s equation needs to be used.
Q6: What is the difference between electric and magnetic field?
|Basis For Comparison||Electric Field||Magnetic Field|
|Definition||Force around the electrical charge particle.||The region around the magnetic where poles exhibits a force of attraction or repulsion.|
|Unit||Volt/meter or Newton/coulomb||Tesla, (Newton × Second) /(Coulomb × Meter)|
|Electromagnetic Field||It is perpendicular to the magnetic field.||It is perpendicular to the electric field.|
|Field Line||Induces on a positive charge and terminate on a negative charge||Generate at north pole and terminate at the south pole.|
|Loop||Electric field lines do not form a closed loop.||Magnetic line forms a closed loop.|
|Type of charge||Negative or positive charge.||North or south pole.|
|Force||Repulsion force on like charges and attraction force on unlike charges.||Repulsion force on like poles and attraction force on unlike poles.|
|Dimension||Exist in two dimensions||Remain in three dimensions|
|Work||Field can do work (the speed and direction of particles changes)||Magnetic field cannot do work (speed of particles remain constant)|
