Current through a battery
The klmn current in the second example is 2 amperes. The current going into a battery or resistor always equals the current coming out of a battery or resistor. The same applies to other circuit components (capacitors and inductors). The reason is conservation of charge. Current is the amount of charge passing a point per unit time.
