Practice Questions

Question 1

What does Kirchhoff’s Junction Rule state about electric current at a junction in a circuit?

Question 2

A current of $3\,\text{A}$ enters a junction, and one branch carries away $1\,\text{A}$. How much current leaves through the other branch?

Question 3

Which physical principle is the main reason Kirchhoff’s Junction Rule works?

Question 4

At a junction, $I_1 = 2\,\text{A}$ and $I_2 = 5\,\text{A}$ flow into the junction, while $I_3$ flows out. What is $I_3$?

Question 5

If $4\,\text{A}$ enters a junction and $1\,\text{A}$ leaves one branch, what does Kirchhoff’s Junction Rule say about the remaining branch?
