By the end of this unit the successful student will be able to:
· Understand the definition of electric current, so they can relate the magnitude and direction of the current to the rate of flow of positive and negative charge. (APIIIC1a)
· Understand conductivity, resistivity, and resistance, so they can:
o Relate current and voltage for a resistor. (APIIIC1b1)
o Describe how the resistance of a resistor depends upon its length and cross-sectional area, and apply this result in comparing current flow in resistors of different material or different geometry. (APIIIC1b3)
o Apply the relationships for the rate of heat production in a resistor. (APIIIC1b6)
· Understand the properties of ideal and real batteries, so they can:
o Calculate the terminal voltage of a battery of specified emf and internal resistance from which a known current is flowing. (APIIIC2b1)
· Understand the behavior of series and parallel combinations of resistors, so they can:
o Identify on a circuit diagram whether resistors are in series or in parallel. (APIIIC2a1)
o Determine the ratio of the voltages across resistors connected in series or the ratio of the currents through resistors connected in parallel. (APIIIC2a2)
o Calculate the equivalent resistance of a network of resistors that can be broken down into series and parallel combinations. (APIIIC2a3) (19-2)
o Calculate the voltage, current, and power dissipation for any resistor in such a network of resistors connected to a single power supply. (APIIIC2a4)
o Design a simple series-parallel circuit that produces a given current through and potential difference across one specified component, and draw a diagram for the circuit using conventional symbols. (APIIIC2a5)
· Apply Ohm’s law and Kirchhoff’s rules to direct-current circuits, in order to:
o Determine a single unknown current, voltage, or resistance. (APIIIC2c1)
· Understand the properties of voltmeters and ammeters, so they can:
o State whether the resistance of each is high or low. (APIIIC2d1) (19-8)
o Identify or show correct methods of connecting meters into circuits in order to measure voltage or current. (APIIIC2d2) (19-8)
