Electric field lines are an essential concept in physics that is used to describe the electric field around a charged object. The electric field is the force that acts between two charged particles and is represented by electric field lines. These lines indicate the direction and strength of the electric field at each point in space. Understanding the properties of electric field lines is crucial to understanding many aspects of electrical phenomena.

One of the most important properties of electric field lines is that they always start from a positively charged object and end at a negatively charged object. If there are no charged objects nearby, the electric field lines will simply radiate outwards from a positively charged object and converge towards a negatively charged object. This is due to the fact that electric charges attract each other.

Another important property of electric field lines is that they never cross each other. If two lines were to cross, it would mean that there are two different electric fields acting at the same point in space, which is not possible. Instead, electric field lines will always run parallel to each other and spread out as they move away from the charged object.

In addition, the density of electric field lines is directly proportional to the strength of the electric field. The closer the lines are to each other, the stronger the electric field is at that point. This is why electric field lines are often drawn closer together near charged objects.

Electric field lines also have a number of other properties that are important in understanding electrical phenomena. For example, the shape of the electric field lines can give an indication of the shape of the charged object. If the object is spherical, the electric field lines will be evenly spaced around it. If the object is cylindrical, the electric field lines will be parallel to the sides of the cylinder.

This video explains the properties of electric field lines in detail, covering important concepts such as the direction and strength of the electric field, the relationship between electric field lines and charged objects, and the density of electric field lines. The video also includes a section on electric field lines in Hindi and Urdu for viewers who prefer those languages. Whether you are a student studying physics at the BSc level or simply interested in learning more about this fascinating topic, this video is sure to provide valuable insights and knowledge.

Sir mujy serf ap ky lecture ke samj ati hy ..ap boht acha samjaty hain ....Thanks

[shahidmehmood]

Thank u so much sir
U r a great teacher

[free..firelover...]

So nice, . Why we study electric field lines ????

[BilalKhan-xvoh]

Thank you sir your lecture cleared my concept

Figure shows, in cross section, two Gaussian spheres and two
Gaussian cubes that are centered on a positively charged particle.
(a) Which of these surfaces has the greatest flux? Give a reason for
your answer.
(b) Which of these surfaces has the weakest electric field? Why?
(c) Also state whether the electric field is uniform along each
surface?

Thank you sir, The lecture helped me a lot and cleared my concepts too....
But I have a question;
Q:Why shouldn't we say that electric field lines are a path followed by a charge?
(I asked this question because in our KPK syllabus for federal board, there is a line written on pg#11
"The electric lines of force are the path followed by a unit positive charge in the field of source charge")
Please elaborate, Thanks!

Sir jessa k ap ne kaha 2 like charges aik dosry ko repul karengy
Negative sign ki electric field lines jo he inward he to ye dono to aik dosry ko attract karna chahye na ?
