sorry, to clarify properly;
the question is three part.
a) i am given an area of SHEET material with dimensions 10mm x 20mm with rho=10`3ohm/m. i have to calculate the thickness required to give a resistance of 5kohms.
l =0.01 x 0.02 x (5000/10`3)...
leakage resistance of capacitor theory help??
i have worked out the answer to my question, yet it seems silly so have convinced myself its wrong. Please help, or tell me if i'm being stupid if you can??
a parallel plate capacitor Er=12, length=10mm, width=5mm, C=100pF...
