The figure shows the current I in a single-loop cicruit with a battery B and resistance R (and wires of negligible resistance).
Then find the order of following at the point a, b and c
(a) The magnitude of the curent,
(b) The electric potential, and
( c) The electric potential energy of the charge carriers (electron), greatest first.

Answer

(a) all equal
(b) b, then a and c equal
( c) a, c equal , b
