15) The circuit below contains 5 light bulbs. The emf is 110 V. Which light bulb(s) is(are) brightest?
A: The one closest to the positive terminal of the battery.
A and C: The bulbs closest to the positive terminal of the battery.
A and B: Because they are closest to the terminals of the battery.
C and D: Because they receive current from A and B and from E.
E: Because the potential difference across E is that of the battery.
16) Blood pressure is normally measured with the cuff of the sphygmomanometer around the arm. Suppose that the blood pressure is measured with the cuff around the calf of the leg of a standing person. Would the reading of the blood pressure be (a) the same here as it is for the arm? (b) greater than it is for the arm? or (c) less than it is for the arm?
