Practice Questions

Question 1

What does Kirchhoff’s Loop Rule state for any closed path in a circuit?

Question 2

In a loop equation, what is the sign of a battery’s potential change when you move from its negative terminal to its positive terminal?

Question 3

Which statement best describes why Kirchhoff’s Loop Rule is useful in circuit analysis?

Question 4

A simple loop contains a battery with emf $12\ \text{V}$ and one resistor with a voltage drop of $12\ \text{V}$. What does Kirchhoff’s Loop Rule predict for the sum of potential changes around the loop?

Question 5

If you choose a direction around a circuit loop and cross a resistor in the same direction as the current, how is the potential change across the resistor usually written?
