I'm sorry, I was one more step ahead, actually and doing an additional sum, so I was wrong. Proceed.

comment I don't understand what we really mean by voltage drop
Your three points are very good ones. To make your third one more specific: "The voltage drop has to do with the energy released PER electron caused by the resistor."

To answer your second question, yes, that is what the Kronecker delta means.

comment Thermodynamics and electromagnetic fields
For the first equation, you have done the summation incorrectly in the first term. Try writing it out more explicitly. You can simplify the second term with the sum further. Pressure is a scalar quantity! I'm sorry if my hint was confusing. I've rephrased it for you.

comment Newtonian Gravity on a Riemannian $3$-Manifold
Could you please edit your question so that it is more readable? Breaking it up into more sentences with a little more detail would greatly enhance the clarity. Thanks!
