36. Three 1/2 ?F capacitors are connected in series as shown in the diagram above. The capacitance of the combination is (A) 0.1 ?F (B) 1 ?F (C) 2/3 ?F (D) ? ?F (E) 1/6 ?F 37. A hair dryer is rated as 1200 W, 120 V. Its effective internal resistance is (A) 0.1 ? (B) 10 ? (C) 12? (D) 120 ? (E) 1440 ? 38. A point charge +Q is inside an uncharged conducting spherical shell that in turn is near several isolated point charges, as shown above. The electric field at point P inside the shell depends on the magnitude of (A) Q only (B) the charge distribution on the sphere only (C) Q and the charge distribution on the sphere (D) all of the point charges
