eS 1) Consider the circuit shown below. Note that this question is not identical to the similar-looking one you answered in the prelecture. 2R The circuit consists of a voltage source V connected to two vertical branches in parallel. The left branch contains two resistors in series: a top resistor of resistance R, and a bottom resistor of resistance 2R. The right branch also contains two resistors in series: a top resistor of resistance 2, and a bottom resistor of resistance R. Points a and b are located between the top and bottom resistors in the left and right branches, respectively, and are connected by a horizontal blue wire. Which of the following statements best describes the current flowing in the blue wire connecting points a and b? Positive current flows from a to b Positive current flows from b to a No current flows between a and b
