After studying the material of this chapter, the student should be able to:
1. Determine the equivalent resistance of resistors arranged in series or in parallel or the equivalent resistance of a series parallel combination.
2. Use Ohm's law and Kirchhoff's rules to determine the current through each resistor and the voltage drop across each resistor in a single loop or multiloop dc circuit.
3. Distinguish between the emf and the terminal voltage of a battery and calculate the terminal voltage given the emf, internal resistance of the battery, and external resistance in the circuit.
4. Determine the equivalent capacitance of capacitors arranged in series or in parallel or the equivalent capacitance of a series parallel combination.
5. Determine the charge on each capacitor and the voltage drop across each capacitor in a circuit where capacitors are arranged in series, parallel, or a series parallel combination.
6. Calculate the time constant of an RC circuit. Determine the charge on the capacitor and the potential difference across the capacitor at a particular moment of time and the current through the resistor at a particular moment in time.
7. Describe the basic operation of a galvanometer and calculate the resistance which must be added to convert a galvanometer into an ammeter or a voltmeter.
8. Describe how a slide wire potentiometer can be used to determine the emf of a source of emf. Given the emf of a standard cell, use the slide wire potentiometer to calculate the emf of the unknown.
9. Describe how a Wheatstone bridge circuit can be used to determine the resistance of an unknown resistor. Given three known resistors and a Wheatstone bridge circuit, calculate the resistance of an unknown resistor.
