EN123 Quiz 0: Sept 4, 2013
take-home honor-system --> solve the problem on your own... can access information

Read over the Resistance Tutorial:
http://www.brown.edu/Departments/Engineering/Courses/En123/CirRevFiles/Resistance2.htm
paying particular attention the the node admittance matrix method
of solving a circuit for node voltages.
Notice that in setting up KCL you need to declare which way you think positive current is flowing in each branch, and those arrows of current determine how to label the voltage difference across the resistor of each branch.
In the circuit below
R1 = 1KΩ, R2 = 2KΩ, R3 = 3KΩ, R4 = 4KΩ, R5 = 5KΩ
IS = 10mA, VL = 5v
Your question: What are node voltages VM1 and VM2?
name________________________________ answer___VM1
= ____________VM2 = ___________volts

Your quiz will be graded by the next class meeting.
It is not necessary for you to take, or get correct answers to, Quiz 0 to pass EN123; we're looking at your work as a way to judge your understanding of resistance in a circuit.
