How to figure out max voltage from resistance of the material between two plates

AI Thread Summary
To determine the maximum voltage of a capacitor, focus on the dielectric strength of the material between the plates rather than its resistance. The dielectric strength is calculated as the breakdown voltage divided by the thickness of the material. For example, polythene has a dielectric strength ranging from 20 to 160 MV/m. The resistance of the material is less relevant for calculating maximum voltage in this context. Accurate calculations of volume may also be necessary for further analysis.

Okay guys, I have a question and I am sure the answer is stupidly obvious but I can't seem to find a equation explaining it. I want to know the max possible voltage of the capacitor based on the distance between the plates, the Area of the plates, and the resistance of the material between the plates in ohms. if it helps the figures I was looking at were dx = .35 (m) A = .5 (m) radius and the resistance of the material between the plates is 1 * 10^11 (ohms) Which gives this material a volume of .27 (m^3)

What you need to know is the dielectric strength of the material, not its resistance. This is given as breakdown voltage / thickness, so for example polythene might be 20-160MV/m.

PS. You might want to check your calculation of volume, not that it is relevant!
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Two capacitors, etc.'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
