Homework: Read Chapter 4 again.
  1. Download or run the Circuits simulation from the web page. Drag a battery, light bulb, switch and several wires from the panel onto the screen. Connect them so that you get current to flow and the light bulb to light. Draw a sketch of your circuit. Hint: The different items connect together automatically; you can separate them by using a control click on the junction.
  2. Click the box for adding a non-contact ammeter. Drag it over different parts of the circuit. What is the current in the circuit? Is it the same everywhere? If the current isn't used up in the circuit, what is?
  3. Click on the box to add a voltmeter. You will notice there are two leads to the voltmeter; this is because it measures the potential energy difference between two locations. What is the voltage difference across the battery? What about the voltage across the light bulb? What about the voltage from one end of a wire to the other end?
  4. Separate one of the junctions and add a resistor. What happens to the current compared to the circuit with no resistor? What happens to your voltage readings?
  5. Replace the battery with the AC source. What is the difference between a battery (which provides DC or direct current) and the AC (alternating current) source?
  6. Add a current chart to the circuit. Move the probe over various parts of the circuit. Describe or sketch what the current is doing, according to the current chart.

Summary of electricity and magnetism:
  1. Voltage causes current to flow (if there is a path = resistance). (Ohm's law).
  2. Current causes a magnetic field. (Ampere's law).
  3. Current + magnetic field causes a force. Electric motors. (Lorentz force).
  4. Force + magnetic field (changing magnetic field) causes voltage. (Faraday's law).
W, Sept.25 In class: Handout problems on Faraday: 1 through 10. Simulation on Faraday's law.
Homework: Read Chapter 4 again;
  1. Download or run the Faraday's Law simulation from the web page. Move the compass and the magnet around. What is the relationship between the white end of the compass needle and the magnetic field of the magnet?
  2. Click on the box to show the field meter. The first number in the box is the total strength of the field in Gauss. How does the field strength vary as you move closer and further away from the magnet?
  3. Now click on the electromagnet tab at the top. This shows a battery producing an electric current in a small coil. Move the compass and coil around. Use the field meter. How is this similar to the field produced by the permanent magnet?
  4. Now click on the AC source to replace the battery with an Alternating Current. Describe the difference in this field compared to the permanent magnet.
  5. Now click on the "Pickup Coil" tab at the top of the simulation. Move the magnet around. Carefully describe how to make the light bulb light up.
  6. Now move the coil and light bulb around. Carefully describe how to make the light bulb light up.
  7. Notice that the light bulb only lights if something is moving. Does the brightness of the bulb (length of the rays coming from it) depend on the speed of motion of either the magnet or bulb?
  8. Now click on the "Transformer" tab at the top of the simulation. What has to happen in this case to get the light to light up?
  9. Click on the AC icon on the right panel in the simulation. This replaces the battery with an alternating source. What is happening in the coil below the AC source? What happens to the light in the light bulb?
  10. Move the AC source coil until it is directly on top of the light bulb coil. Is the light brighter or less bright?
  11. Change the number of loops attached to the light bulb by clicking in the right panel. What is the effect on the brightness of the bulb in the case of more loops?
  12. Change the number of loops attached to the light AC source by clicking in the right panel. What is the effect on the brightness of the bulb in the case of more loops?
  13. Now click on the "Generator" tab at the top of the simulation. Turn on the water flow from the tap by moving the slider on the top of the tap. Describe what is happening.
  14. Is the current generated in the bulb AC or DC? This is how water from a dam generates electricity. In coal or gas fired plants steam is generated by boiling water and the steam turns a magnet (usually an electromagnet) to generate current.
