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 resistance, so they can:
- Relate current and voltage for a resistor. (APIIIC1b1)
- Apply the relationships for the rate of heat production in a resistor. (APIIIC1b6)
- Understand the properties of ideal and real batteries, so they can:
- 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:
- Identify on a circuit diagram whether resistors are in series or in parallel. (APIIIC2a1)
- Determine the ratio of the voltages across resistors connected in series or the ratio of the currents through resistors connected in parallel. (APIIIC2a2)
- Calculate the equivalent resistance of a network of resistors that can be broken down into series and parallel combinations. (APIIIC2a3)
- Calculate the voltage, current, and power dissipation for any resistor in such a network of resistors connected to a single power supply. (APIIIC2a4)
- 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 to direct-current circuits, in order to:
- Determine a single unknown current, voltage, or resistance. (APIIIC2c1)
- Understand the properties of voltmeters and ammeters, so they can:
- State whether the resistance of each is high or low. (APIIIC2d1)
- Identify or show correct methods of connecting meters into circuits in order to measure voltage or current. (APIIIC2d2)
