Find the effective area required to build such a capacitor

AI Thread Summary
To build a 1 Farad capacitor using Strontium Titanate as the dielectric, one must consider the dielectric strength to determine the minimum gap for a maximum voltage of 5 volts. The capacitance equation for a dielectric, C=EoA/d, is essential for calculating the effective area required. Participants in the discussion highlight the importance of using the correct capacitance formula that includes the dielectric material. The challenge lies in fitting the calculated area into a compact volume of only a few centimeters. Understanding these principles is crucial for successfully designing the capacitor.

Homework Statement



One can buy 1 Farad capacitors which are only a few centimeters long. Speculate
on how you can build such a capacitor. Assuming that you are using Strontium
Titanate as the dielectric find the minimum gap for a maximum voltage of 5 volts.
Find the effective area required to build such a capacitor. How can you put this area
into a volume that is only a few centimeters

Homework Equations


C=Q/V
C=EoA/d

The Attempt at a Solution


to find the minimum gap, i think we can start from dielectric strength??

The Attempt at a Solution


Aren't you forgetting something??
 
i don't have any idea about how to solve that problem so a little help
 
You need to start by looking at the equation for the capacitance of a capacitor with a dielectric. The equation you listed is for capacitance with no dielectric.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
