the
battery, becoming more positive
by 40 V.
Coming down through
R, we
move from positive
to
negative
so add
-12.25
V, and,
through
R

-27.75
V,
reaching
the
starting point
again. Check: 40-12.25-27.75
- 0.
Taking another clockwise route
via R

, we get
13.54-27.75
+ 14.21 = 0. And so on for any
closed loop.
