Practice Problems: Kirchhoff's Rules
Click here to see the solutions
1. (moderate) A student claims that a loop rule applied to a simple electric circuit confirms the principle that charge is conserved. Is the student correct? Explain your response.
2. (moderate) A simple electric circuit is analyzed by a student such that the following loop rule accurately describes how the electric potential changes in the loop.
12 - 15I - 25I - 9I = 0
Determine the current in the loop and then create a graphical representation of this loop rule. Assume that one point in the loop is grounded.
