Question

Use principles of physics to solve the problem and then verify your answer using the simulation.

(a) In this simulation Kirchoff's Rules are used to solve for the three unknown currents in a multiloop circuit. What are these rules, and which conservation laws are they equivalent to? Select all the correct statements from the list below.
Kirchoff's Junction Rule states that the sum of the currents coming in to a junction must equal the sum of the currents flowing away from the junction.
Kirchoff's Junction Rule states that the net current coming into one junction in a circuit must equal the net current coming out of another junction.
Kirchoff's Loop Rule states that the sum of all the potential differences between any two points in a circuit is zero.
Kirchoff's Loop Rule states that the sum of all the potential differences around any complete loop in a circuit is zero.
Kirchoff's Junction Rule is a statement of the Law of Conservation of Energy.
Kirchoff's Junction Rule is a statement of the Law of Conservation of Charge.
Kirchoff's Loop Rule is a statement of the Law of Conservation of Energy.
Kirchoff's Loop Rule is a statement of the Law of Conservation of Angular Momentum.

Explanation / Answer

Junction rule - The total current flowing into a junction equals the total current flowing away from the junction. Current is the rate of flow of charge, so the junction rule is infact a statement of the conservation of charge.

Kirchoff's Loop Rule: The sum of all the potential differences around a closed loop equals zero. This is a statement of conservation of energy.
