1- tarts from the fundamental definition of voltage?
Does the explanation start from the definition of voltage, the integral of \vector{E} dot \vector{dl}?
2- This criterion is linked to a Learning OutcomeThis item only applies if this is a circuits problem!
IF this is a circuits problem, does the explanation start from Kirchoff's Laws?
3- OutcomeIs the path of interest identified?
The vector dl is a small step along this path.
4- This criterion is linked to a Learning OutcomeIs the electric field drawn along the path of interest?
To find the voltage, you need to dot the displacement (\vector{dl}) with the electric field at each step along
the path.
5- This criterion is linked to a Learning OutcomeIs the expression \vec{E} dot \vec{dl} correctly reduced to a
scalar quantitiy?
The sign must be correct for full credit. For clarity I recommend drawing both vectors.
6-This criterion is linked to a Learning OutcomeIs the integral of \vec{E} dot \vec{dl} evaluated correctly for
the problem?
This does not have to be quantitative (although it can be). It can also be an argument for a zero value, a
non-zero value, a greater than/less than comparison, etc.
7- This criterion is linked to a Learning OutcomeIs there a discussion about the answer as it relates to the
stated problem?
