I received the following after each of my last two posts. What is
happening? Should I worry?

| I might have added that it follows from the choice 1) that there is a
| potential DROP of V = iR across the resistor in the direction chosen for
| positive i. Likewise, it follows from the choice 2) that there is a
| potential DROP of V = q/C from the capacitor plate chosen in 2) to carry
q,
| to the other capacitor plate. These signed potential differences must be
| heeded in writing the loop equation.
|
| I also add that in making the choices 1) and 2) you are NOT forecasting
the
| direction of i, or the sign of q; you are simply DEFINING the meaning
| (including sign) of these quantities. Properly written loop equations
will
| be valid whatever circumstances dictate to be the actual signs of these
| quantities.
