Question A 15 |
---|
For questions A13–A15 consider the resistor network in the diagram below. The resistances and sources are known in this network. Write a linear equation that expresses the current through the current source in terms of the loop currents in the diagram. |
Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you? |
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it! |
Hint |
---|
Recall that Kirchoff's current law states that "current in" equals "current out" for any node. |
Checking a solution serves two purposes: helping you if, after having used the hint, you still are stuck on the problem; or if you have solved the problem and would like to check your work.
