comment Why is it said that without quantum mechanics we would not have modern computers?
@DanS The implied meaning is that one does not need to have a good understanding of QM to utilize vacuum tubes. However, it is not possible to manufacture advanced technology nodes (below 32 nm) without a good grasp of what secondary effects to expect. Even at much higher technology nodes (and in discrete circuits) Body Effect is a very important phenomenon in analog circuits, which is described via Energy Band Theory.

comment Do holes have physical existence?
Yes, it is purely theoretical. However, treating them as positively charged particles makes the equations and theory convenient and symmetrical. For the most part in semiconductor device theory, we use the same equations and relations for holes as electrons, with different mobility factors and a sign change every now and then.

comment Electrical properties of molten gallium arsenide
Resistivity of Gallium Arsenide is very, very dependent on temperature, since it directly affects the concentration of intrinsic carriers. There are formulas to calculate the carrier concentration at any given temperature for Gallium Arsenide. However, I do not know of any applications of GaAs in liquid state and can not be of help in that issue.

comment Why does an armature of a generator rotate?
It is D. Armature of the generator is externally rotated, so that the coil on the armature cuts the magentic field lines of the field winding, generating a current.

comment How does current flow in a irregularly shaped heterogeneous resistor?
Also, in the case of a macroshock, forming the conduction path from one hand to the other will be deadlier than forming the conduction path from a hand to a foot, since the conduction path will not involve heart, and will require a very large amount of current to cause it to go into fibrillation. This is how most people survive lightning strikes.
