Which statement best expresses the relationship among electric currents at a point where several conductors meet and no charge accumulates at that point?
(a) The sum of the potential differences around any closed loop that includes the point is zero.
(b) The magnitude of the current is the same in every conductor that meets at the point.
(c) The algebraic sum of the currents entering and leaving the point is zero.
(d) The product of all currents entering the point equals the product of all currents leaving the point.
