Question

Does shape of the capacitor determine how fast the capacitor can discharge? How can we speed up the movement of electrons or is that set by physical electron properties?

Answer 1

Yes, the shape of capacitor determines that how fast capacitor can discharge. When start discharging, the amount of charge will be Q and heat dissipate will be q*q/2c

So inverse of capacitance.

And C = £A/D

Where A is facing area of both the plates of capacitor and D is distance between the plates.

So by decreasing C we can increase the rate of discharging.

So if facing plate area get change then c can decrease.

And this can be change by changing the shape of capacitor.

For speeding up movement, v will be fix

So energy of capacitor will be 1/2cv^2

So by increasing C.

C can be increased by decreasing the distance between plates.

So if plates closed together then we can speed up electrons.
