CIRCUITS

Objectives

 APPB (REBOOT)  (Web view)

After studying the material of this chapter, the student should be able to:
1. Explain how a simple battery can produce an electrical current.
2. Define current, ampere, emf, voltage, resistance, resistivity, and temperature coefficient of resistance.
3. Write the symbols used for electromotive force, electric current, resistance, resistivity, temperature coefficient of resistance and power and state the unit associated with each quantity.
4. Distinguish between a) conventional current and electron current and b) direct current and alternating current.
5. Know the symbols used to represent a source of emf, resistor, voltmeter, and ammeter and how to interpret a simple circuit diagram.
6. Given the length, cross sectional area, resistivity, and temperature coefficient of resistance, determine a wire's resistance at room temperature and some higher or lower temperature.
7. Solve simple dc circuit problems using Ohm's law.
8. Use the equations for electric power to determine the power and energy dissipated in a resistor and calculate the cost of this energy to the consumer.
9. Distinguish between the rms and peak values for current and voltage and apply these concepts in solving problems involving a simple ac circuit.

AP TEST INFO GRAPHIC

• You will be allowed to use a four-function, scientific, or graphing calculator on the entire AP Physics 1 Exam – including both the multiple-choice and free response sections. Check the list of approved graphing calculators (which also includes a list of devices that are not allowed)
• Bring a calculator you are familiar with. It is a good idea to bring extra batteries .You may bring up to two calculators.
• Students may not share calculators.
• Tables containing equations commonly used in physics will be provided during the entire AP Physics 1 Exam. Because the equation tables will be provided, you will not be allowed to bring your own copies into the exam room.

For solving problems and writing essays, a sophisticated scientific or graphing calculator, tables of equations, or the availability of stored equations, is no substitute for a thorough grasp of the physics involved. In scoring the exam, little or no credit will be awarded for simply writing down equations or for answers unsupported by explanations or logical development.
