Question 1.
What is Kirchhoff's junction rule?
Show hintHide hint
Remember the conservation of charge.
Question 2.
State Kirchhoff's loop rule.
Show hintHide hint
Think about energy in a circuit.
3Question 3.
What does the junction rule state?
- The total current entering equals the total current leaving
- The potential difference must equal zero
- Current must be constant in a circuit
Show hintHide hint
Think about how currents interact at junctions.
4Question 4.
Is Kirchhoff's loop rule valid for any closed loop?
- True
- False
Show hintHide hint
Consider implications of energy conservation.
Question 5.
Analyze a quantitative circuit problem where you need to determine the current through each branch of a mixed circuit including multiple sources and resistors.
Show hintHide hint
Setting a consistent direction for current will simplify solving.
Question 6.
In a Wheatstone bridge, explain how to achieve a null deflection and derive the relationship between the resistors.
Show hintHide hint
Use symmetry to simplify your calculations.
