QUESTION 8 Gauss's Law describes the following relationship (select the correct answer): ca. Electric flux through a closed surface and charge enclosed by the surface. b. Phase angles between current and voltage in capacitors and inductors. c. Electromotive force induced in a conductive loop by variation of a magnetic field. d. Voltage difference across a resistance when current is flowing through the resistance. QUESTION 9 "Static" electricity can be described as (select the correct answer): ca. The buildup of current inside a resistor with a very high resistance value (at least 10 million Ohms). b. An imbalance in the number of positive and negative charges, causing a potential difference between an object and its surroundings. c. Electric current that gets "stuck" in a circuit that is abruptly unplugged from a voltage source. d. Energy stored in a charged battery that has not been connected to a load. QUESTION 10 Which of the following statements about conductive materials is incorrect? 1. Charges in a conductor move in response to an electric field. The electrical resistance of a conductor is always equal to zero ohms. 3. Current flow in a conductive material is due to the movement of positive and/or negative charges. 4. Examples of conductive materials include silver, aluminum, and gold.
