Multiplechoice questions may continue on the next column or page – find all choices before answering. The due time is Central time. Note: For 003, give your answer in units of muC(E6 C) 001 (part 1 of 2) 10 points Hint: The resistance to the right of A B is the same as the resistance to the right of AB; that is, R AB = R → A B . 1 . 9 Ω 1 . 9 Ω 1 . 9 Ω 8 . 75 Ω 8 . 75 Ω 8 . 75 Ω 5 . 4 Ω 5 . 4 Ω 5 . 4 Ω A A B B What is the resistance R AB between the terminals A and B of this infinitely repeating chain of resistors. Answer in units of Ω. 002 (part 2 of 2) 10 points If a 28 . 5 V battery is connected between A and B , what is the current through the 8 . 75 Ω resistor nearest A and B ? Answer in units of A. 003 (part 1 of 1) 10 points In the figure below the battery has an emf of 15 V and an internal resistance of 1 Ω ....
