No Takers?
No physics majors? :smile: I'm not trying to trip anyone up. I am being sincere. Should I reword the question? How about this:
Take several metals of different conductivity, with the same thickness, intimately layered on each other. What is the total conductivity...
Given different conductivity values, sigma1, sigma2, etc.
Given the thicknesses are the same.
Given the layers are in intimate contact with each other. (No air gaps.)
Is the whole conductivity for the stackup of layers follow this:
1/sigmatotal = 1/sigma1 + 1/sigma2 + ... ?
Is...
