Homework Answers
Current is being defined as the charge flow per second through a given section of the circuit. As per Kirchoff's Junction rule, the sum of the total current at a junction of the circuit is always zero. It means that the incoming current at the junction is equal to the outgoing current from the junction. That is the total charge flow per second towards the junction is equal to the total charge flow per second away from the junction. This is in accordance with the Law of conservation of charges. So, Kirchoff's junction rule is the answer.

1. Kirchoff’s Rules are defined in terms of loops and junctions. How would you define a “loop” in a circuit? What is a junction? 2. What happens to the reading of the ammeter if you reverse the connections? The voltmeter? 3. Recall that current is just the motion of electric charges. The Junction rule is a practical manifestation of what more fundamental conservation law? What conservation law implies the loop rule? 4. Write a junction equation for the point B1...

State whether the following are true or false, and explain why? Any equipotential surface of a point charge is a sphere with the charge at its center. Electric field lines run perpendicular to a surface of a conductor. The equivalent capacitance of two capacitors in series is smaller than each individual capacitor. The junction rule is based upon conservation of momentum, whereas the loop rule is based upon the conservation of charge. Kirchhoff junction rule is valid for any multiloop...
