We have learned how to apply Kirchoff's rules. I am sure that this problem is a lot easier than I am making it out to be but we have not done many examples in class.
In the above circuit:
V1 = 12.00 V V2 = 6.00 V V3 = 3.00 V
R1 = 220.0 R3 = 270.0
Because of the direction of the batteries, a student looking at the above circuit makes this guess for the direction of current across resistors R1 and R3. Is the student...
