Unformatted text preview: Physics 2102, February 28, 2011. Activity 1: The figure shows a circuit with a battery B ,a resistance R, and current i . Neglect resistance in the wires. (i) Should the emf arrow at B be pointing leftward or rightward? Draw your answer on the figure. (ii) At points a , b , and c , rank the magnitude of the current i . i a > i b > i c i b > i c > i a i b > i c = i a i a = i b = i c (iii) At points a , b , and c , rank the magnitude of the electric potential V . V a > V b > V c V b > V c > V a V b > V c = V a V a = V b = V c Activity 2: Three resistors, where R 1 > R 2 > R 3 , are connected in series. Rank the potential difference across them, greatest first: V 1 > V 2 > V 3 V 3 > V 2 > V 1 V 1 = V 2 = V 3 Physics 2102, February 28, 2011.
