Practice Questions
Question 1
What does Kirchhoff’s Junction Rule state about electric current at a junction in a circuit?
Question 2
Which physical principle is the basis of Kirchhoff’s Junction Rule?
Question 3
At a junction, $I_1 = 3\,\text{A}$ and $I_2 = 2\,\text{A}$ flow into the junction. What current must flow out if only one branch carries the outgoing current?
Question 4
Which equation correctly represents Kirchhoff’s Junction Rule for a junction where currents $I_1$ and $I_2$ enter and $I_3$ and $I_4$ leave?
Question 5
In a junction, if the current entering is $4\,\text{A}$ and one outgoing branch carries $1\,\text{A}$, what is the current in the other outgoing branch?
