How to find the maximum voltage that can be placed across a capacitor.

AI Thread Summary
To find the maximum voltage that can be applied across a capacitor, the dielectric strength is a key factor. For the given strontium titanate filled capacitor, the dielectric strength is 8.0 kV/mm, which indicates the maximum voltage per unit thickness. With a plate separation of 0.070 mm, the maximum voltage can be calculated by multiplying the dielectric strength by the separation distance. This results in a maximum voltage of 560 V across the capacitor. Understanding the relationship between dielectric strength and plate separation is crucial for determining the safe operating voltage.

How do you find the maximum voltage that can be placed across the capacitor?

It is a parallel plate strontium titanate filled capacitor, that has plates of area 0.78 m^2 and a separation of 0.070 mm. It also has a dielectric constant of 310 and a dielectric strength of 8.0 kV/mm.

I already figured out that the capacitance is 30.570 * 10^-6 F

But i can't seem to figure out how to find the max voltage.

The dielectric strength gives you the answer.Look at the units.What do they tell you?
 
thanks!
 
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...
