Suggestions for this week's quiz (Unit 9 Quiz#1):

This week's quiz on Unit 9 material is tentatively scheduled for Friday, March 3. The quiz is substantially length - probably covering the front side of a second sheet of paper - and worthy of up to 50 pts. You can expect a large number of MOP questions. The equations for current (I=Q/t), voltage(V=Delta E/Q), V=I*R, and power (P=I*V, P=Delta E/t) will be given. Other than a calculator, no other helps will be provided nor allowed. Students can expect the following concepts, skills, and problem-types to be assessed on this quiz:

  1. Identify and describe the requirements for a circuit. (Hewitt, Ch 34.1-3; Packet, pp. 2 and 9; MOP, module 1)
  2. Define current and know its units; use an understanding of current to determine the amount of current at a given location in a circuit if given the appropriate information; know that current is everywhere the same; identify the direction of the conventional current through a circuit; compare this direction to the direction which electrons actually travel. (Hewitt, Ch 34.1-2; Packet, pp. 1, 3-4 and 9-10; MOP, module 1)
  3. Know (and believe) that the source of electrons flowing in a circuit are the atoms of the wires and conducting parts; distinguish between current and drift speed; know that the drift speed of an electron is abnormally low. (Hewitt, Ch 34.9-10; Packet, pp. 1 and 9-10; MOP, module 2)
  4. Explain the role of the battery/power supply in an electric circuit; explain how utility companies are a source of electric energy but not a source of electrons; describe energy transfer in electric circuits. (Hewitt, Ch 34.3; Packet, pp. 5-6 and 11-13; MOP, modules 2, 3)
  5. Identify, refute, and correct common misconceptions concerning charge flow through circuits. (MOP, modules 1 - 3)
  6. Define electric power and describe factors which effect the electric power consumption; use electric power equations and energy costs to analyze the costs of meeting the electricity demands for an average household. (Hewitt, Ch 34.11; Packet, pp. 23-24; MOP, module 6)
  7. Explain the cause and effect of electrical resistance in circuits; use R=V/I relation to describe factors effecting the electric current and solve simple computational problems. (Hewitt, Ch 34.4-6; Packet, pp. 7-8, 15-16, and 22; MOP, modules 4, 5)
  8. Distinguish between series and parallel connections in terms of their definitions and characteristics; to identify a series and parallel circuit if given a circuit diagram or a verbal description. (Hewitt, Ch 35.1-4; Packet, pp. 25-27; MOP, module 7)
  9. Determine the equivalent resistance of a series circuit if given individual resistance values; determine information about current, battery voltage, or the voltage drop for an individual resistor if given other circuit quantities; determine an individual resistance value for a series circuit if given voltage and current information. (Hewitt, Ch 35.3; Packet, pp. 27-30; MOP, modules 7, 9)
