Unformatted text preview: of the following best describes the current flowing in the blue wire connecting points a and b? Which of the following best describes theB. Positive current flows from b connecting points a and b? current flowing in the blue wire to a A. Positive current flows from a to b C. No current flows between a and b I1R – I2 (2R) = 0 I2 = ½ I1 I4R – I3 (2R) = 0 I4 = 2 I3 a: I1 = I + I3 b: I + I2 = I4 I1 ­ I3 + ½ I1 = 2I3 I1 = 2I3 I = +I3 Physics 212 Lecture 10, Slide 24 Physics 212 Lecture 10, Slide Prelecture Checkpoint What is the same?

Checkpoint 3b In which case is the current flowing in the blue wire connecting points a and b the largest? A. Case A B. Case B C. They are both the same “Case A has a lower Req” “The resistors have a value of 4R in Case B, so the current will be more apt The to bypass this section of the circuit” to “The total resistance in the path taken is the same for both” Physics 212 Lecture 10, Slide 27 Physics 212 L...
