Preview - Modeling Electrostatics Using Netlogo

Part II:

  1. Put the number of positive charges @ 100 and hit Setup.
  2. Wait for the charges to show up on the screen.
  3. Set the “line-position” slider to 10 and click on the put-line button.
  4. Hit the go button until the Electric Pressure line levels off.
  5. Click on the fade-line button and hit the go button until the Electric Pressure line levels off.
  6. Record the values from the Monitor windows in the table below.

Questions

Please answer the questions below.

Repeat with different “line-position” values and fill in the table below.

Compare leveled off values after fade-line versus before fade-line for when “line-position” < 40.

How did Electric Potential change?

How did the total PE change?

How did number of charges to the left of the “line-position” compare to number of charges to the right?

How did PE to the left of the “line-position” compare to PE to the right?

Which side of the “line-position” is capable of doing more work?

Since Electric Potential is measured in Joules/Coulomb (Volt), how is a “D” cell battery different from a “AA” battery if they are both 1.5 Volts?

In the same circuit of lighting a bulb or running a motor, how would a “D” cell battery be different from a “AA” cell battery?
