Name: Recitation Instructor: The batteries and resistors in the circuit below have the follow ing values: V1 = 9.0 V, V2 = 3.0V, R1 = 10 0, R2 = 20 Q, and R3 : 45 Q. What is the current 1'; that ows through resis tor R2? For the representation, make sure that you explicitly draw/label all of the loops and junctions that gure into your equation work. For the limit check, investigate what happens to 1'2 if the rst resistor becomes extremely large (R1 ) 00). If you are unsure how to apply this limit check to your symbolic answer, it might be helpful to divide through by R1.
