While analyzing the currents within a circuit containing multiple components (such as batteries, resistors, etc.), which of the following statements concerning currents flowing into a single junction must be true?
a) The sum of the currents entering the junction must equal the total current through the battery.
b) The sum of the currents entering the junction must equal zero.
c) The sum of the currents entering the junction must equal the sum of the currents exiting the junction.
d) The currents entering the junction must follow only one of the possible exit paths.
e) The currents entering the junction may exit back along the path from which they entered
Ans: c) The sum of the currents entering the junction must equal the sum of the currents exiting the junction.
