1) “Print Blank Report or type the blank report exactly the same” used as a lab report. Watch the video to get your data for the blank data report!

The lab has been recorded as the directions that follow:

2) The source of the electric current within this lab is provided by one or more 1.5 volt batteries located at the top of the screen. Although their ratings are noted as 1.5 volt, in reality they will vary from that value. Turn on the voltmeter by clicking on the button at the base of the unit and move it closer to the circuit diagram. Drag the black clip from the voltmeter over to the clip marked “a” and attach it (just release it). Now drag the red clip from the voltmeter over to the far right bottom of the screen and attach it to the clip marked “h”. Record the voltmeter value in volts. This is the voltage of the circuit. Release the two voltmeter clips.

3) Turn on the Ammeter and move it closer to the circuit. The circuit diagram has the letter “A” in a circle near the bottom of the screen. This is a symbol that indicates where the ammeter should be attached. Attach the ammeter’s black clip to clip “g” and the red clip to clip “h”. Since at this time the circuit is not complete, a reading of 0 should be noted.

4) Make sure the wire “jumper” is in place by dragging it to the right. This closes the upper part of the circuit. There are three positions that resistors can take in the circuit. They are labeled “1”, “2” and “3” and have a light gray rectangle around their location. Along side of the rectangle is the symbol for a resistor. Drag resistor “A” over and drop it into the rectangle symbol marked “2”. It should clip in place and you should get a reading on the ammeter. Record this reading as shown in amps. Put the resistor “A” back and place resistor “B” in its place. Record the reading. Lastly record the value for resistor “C”. Put resistor “C” back.

5) Slide the “jumper” over to the left and open up the circuit between “a” and “b”. Place resistor “A” in slot “1” and resistor “B” in slot “2”. Record the value on the ammeter. These two resistors and now in a series configuration. Put the resistors back.

6) Slide the “jumper” over to the right and close the circuit between “a” and “b”. Place resistor “A” in slot “2” and resistor “B” in slot “3”. Record the value on the ammeter. These two resistors and now in a parallel configuration. Put the resistors back.

7) Slide the “jumper” over to the left and open up the circuit between “a” and “b”. Place resistor “C” in slot “1”, “A” in slot “2” and resistor “B” in slot “3”. Record the value on the ammeter. The resistors are in a combination series and parallel configuration. Keep the resistors in this position for the next procedure.

8) Connect the voltmeter’s black clip to clip “a” above resistor “C”. Connect the red clip to clip “b” below resistor “C”. This now measures the voltage across resistor “C” in this circuit. Record the voltage. Move the voltmeters clips to clips “c” and “e” across resistor “A”. Record the voltage. Move the voltmeters clips to clips “d” and “f” across resistor “B”. Record the voltage. NOTE: if you get a negative voltage, reverse the voltmeters clips.
