Hello everyone,
I had a question regarding a voltage breakdown equation that I saw in a book. It helped me to try and solve question 10 in the "Conductors and Insulators" worksheet linked here http://www.allaboutcircuits.com/worksheets/candi.html. Here is the equation:
Vmax = Emax * d
Where,
d = thickness of insulator
Emax = dielectric strength of insulating material
Vmax = breakdown voltage
It's more of a clarification then anything else, I was wondering if the dielectric strength is to remain constant, then increasing the thickness of the material would increase the breakdown voltage due to proportionality, however, doesn't increasing the thickness of a material reduce its electrical resistance? Or is that only for conductors?
I looked on the forum and couldn't find anything specific, mostly on lightening, zener/diode voltage breakdown, and transistor voltage breakdown.
If anyone could make this clarification, I would appreciate it. Thank you.
