Uniform Electric Field (3 of 9) Potential Difference due to Parallel Plates: An Explanation

Gives an introduction to potential difference for charged parallel plates.

When two metallic plates are set a distance apart and then are attached to a potential difference, a battery for example, one plate will have a positive charge and the other plate will have a negative charge. The electric field will be directed away from the positive plate and toward the negative plate. The electric field between the plates is uniform throughout. That means the electric field strength is the same everywhere inside the parallel plates. Only at the ends of the plates will it show a non-uniform field. Such a system can be referred to as a parallel-plate capacitor.

Work must be done to move charges from one plate to another. The work can be done on the charged particle either by an external force or by the electric field. The work done on the particle will be equal to the potential energy given to the particle. Using the law of conservation of energy (initial potential energy = final kinetic energy) the velocity of the charged particles can be determined. The acceleration of the charged particle in the electric field can be calculated using newton's second law. Because there is a uniform electric field between the plates, the charged particle will experience uniform acceleration.

Thank you thank you thank you thank you THANK YOU! Three weeks I've been trying to understand this. No one has taken the time to go over it as slowly and in as much detail as you. This is perfect for someone who needs a very patient explanation of the concepts. Very nicely done!

Haven't you always want to the difference is?

[Caravanseraii]

Thank you so much i know this is an old video but it helped clear my concepts thank you sir

[LasisiOlushola]

You deserve all the good things in life🙏🏽 gracias

[roelchristy]

I love the way you explain everything I am from India

[linabouzida]

Does this mean the electric field can be calculated with the distance and potential difference between the capacitors? From the formula ∆V=Ed rearranged to --> E=∆V/d ?

Sir, the electric field in a battery is uniform? How do we know the amount of electric potential each pole have? Just knowing the charge of each pole? Thanks for your videos.

Thank you really really thank you for clearing our concepts...!😊

[edesabehaj]

is this the same as finding the potential difference between the plates of a conductor?

[abhishekpawarpoems]

In my book the potential difference is 0 btwn the plates how???
