Capacitor Charge Demo: Oscillating Ball

This is a demonstration of capacitor charge, carried out by suspending a ball between two capacitor plates of opposite charges. When the ball touches one plate, it acquires charge of the same sign as that plate. The ball is then attracted to the other plate, acquires charge of the same sign as that plate, and returns to the first plate, and so on, the result being fast oscillations of the ball between the two plates.
This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.

Thanks for these amazing experiments..
Love from India ❤️

Hi❤

[@PROkillC]

Can we use a battery for the potential difference?

[@greenmirror5555]

you should slow motion camera/white board the discharge arc moment events before/as the change in charge process happens.

[@sourabhmushre7771]

How much force is generated b/w the plates?

[@DreamingConcepts]

What if you keep the ball locked in between without touch any of the sides.
What happens as the capacitor charges more and more?

[@ifrazali3052]

I think if the locks are strong enough then nothing will happen except for the sparks
