Kirchhoff's Current Law Quiz

What does Kirchhoff's Current Law (KCL) state?

• The sum of all currents entering a junction equals the sum of all currents leaving the junction.

• The sum of all voltages around a closed loop is zero.

• The current in a circuit is directly proportional to the voltage.

• The resistance in a circuit is inversely proportional to the current.
