Assuming it's the same lattice vibration you are talking in the FAQ section:
Is there a relation between the electrical and optical resistance for a given material? Does the electric resistance change if the material is placed under light?
Is there a way to experimentally see the lattice...
What causes electric resistance for a material (in terms of molecular or atomic level)?
Also, it should be possible to derive the resistance of a material by it's atomic/molecular properties theoretically, right? (without using voltage and current).
Did not understand the double voltage concept. There must be something incorrect in my understanding. Cannot figure out what.
Zn1- Zn side of first battery
Mn1 - Mn side of first battery
///ly, for the second battery.
Let the connection be as follows:
Zn1: Mn1 - Zn2: Mn2
Can I assume the -ve and +ve side chemicals should be separated by insulated walls? If the water is pure, is there need to separate it?
Also, there will be an electric current even if the + side is unconnected, as long as we create a path for the electrons to discharge, right?
As far as I know, the brain generates electric pulses to communicate. If a human being is electrically grounded, how could the charge flow or get created in his brain? A grounded man shold be brain dead :), right?
