PHYSICS 102B LAB:  ELECTRIC CIRCUITS

Professor Jon Satko

For this lab, go to the website OhmZone.

http://www.article19.com/shockwave/oz.htm

In this activity, you will learn all about electric circuits.  First, read the introductory page. 

To access the menu of the fourteen pages that you will do, click on “The Hand.”  Read each page.  Your writing assignment starts with the 6^th page, Equivalent Resistance in a Series Circuit.  Your lab write-up will consist of diagrams of circuits that you design, and answers to various questions on each page.

#6: Equivalent Resistance in a Series Circuit

After reading the page, you will design your own circuit.  To do this, click on “Clear” at the bottom of the page.  Draw a schematic of your circuit.

What is the total R_eq?

Use Ohm’s Law to predict the current.

Check the current with the ammeter.  (It should match your predicted current.)

#7:  Equivalent Resistance in a Parallel Circuit

Draw a schematic of your circuit.

What is the total R_eq?

Check the R_eq by placing the mouse pointer over the battery.

#8:  Kirchhoff’s Current Law

Draw a schematic of your circuit.

Test the given equation using your circuit.

#9:  Current in a Series Circuit

Draw a schematic of your circuit.

Test the given equation using your circuit.

#10:  Current in a Parallel Circuit

Draw a schematic of your circuit.

Test the given equation using your circuit.

#11:  Kirchhoff’s Voltage Law

Draw a schematic of your circuit.

Test the given equation using your circuit.

#12:  Voltage in a Series Circuit

Draw a schematic of your circuit.

Test the given equation using your circuit.

#13:  Voltage in a Parallel Circuit

Draw a schematic of your circuit.

Test the given equation using your circuit.

#14:  Short Circuit

No write-up is necessary for this part.
