QUESTION 1 Which of the following statements about insulating materials is correct? a. The electric field from a charged object is able to penetrate through an insulating material. b. Silver and copper are good insulators. c. Insulating materials exhibit a linear relationship between voltage and current. Insulators can be used to increase the amount of current that can flow through a resistor without increasing its temperature. d. QUESTION 2 Assume that some amount of negative charge is transferred to a solid metal conducting sphere that is initially uncharged. The sphere is located in a region that is free of any electric or magnetic fields. Which of the following statements regarding the behavior of the charges is correct? 1. The charges will become evenly distributed throughout the sphere and the volume charge density inside the sphere will be uniform. 2. The charges will remain concentrated in the area of the sphere where the transfer took place. The surface charge density will be greater in this area. 3. The charges will evenly distribute on the outer surface of the sphere and the surface charge density of the sphere will be uniform. 4. The charges will all concentrate at the center of the sphere and the surface charge density of the sphere will be zero. QUESTION 3 The direction of the magnetic field surrounding a long, straight current-carrying conductor can be visualized by using: Ca. Faraday's Law b. Right-hand Rule c. Oscilloscope d. Multimeter
