➁ Connect the 10 Ω resistor (brown, black, black)
between the component spring at the left hand edge
of the inductor coil, and the second component
spring to the left of the top banana jack.
➂ Connect another 5 inch wire lead between the
component spring nearest to the one in which one
end of the 10 Ω resistor is connected, and a compo-
nent spring nearest to the bottom banana jack at the
lower right corner of the AC/DC Electronics Lab
Board.
➃ Put alligator clips on the banana plugs of both
Voltage Sensors. Connect the alligator clips of
Voltage Sensor “A” to the component springs at both
sides of the inductor coil.
➄ Connect the alligator clips of Voltage Sensor “B” to
the wires at both ends of the 10 resistor.
➅ Connect banana plug patch cords from the output of
the Power Amplifier to the banana jacks on the AC/
DC Electronics Lab Board.
Part III: Data Recording
➀ Use the multimeter to measure the resistance of the
inductor coil. Record the resistance in the Data Table.
➁ Use the multimeter to check the resistance of the 10 Ω resistor. Record the resistance in the Data
Table.
➂ Turn on the power switch on the back of the Power Amplifier.
➃ Click the “ON” button ( ) in the Signal Generator window. The power amplifier output will
begin.
➄ Click the “REC” button ( ) to begin data recording.
• Data recording will end automatically after 0.02 seconds. Run #1 will appear in the Data list in the
Experiment Setup window.
➅ Click the “OFF” button ( ) in the Signal Generator window. Turn off the power switch on the
back of the Power Amplifier.
Analyzing the Data
• The voltage across the resistor is in phase with the current. The voltage is also proportional to
the current (that is, V = IR). Therefore, the behavior of the current is studied indirectly by
studying the behavior of the voltage across the resistor (measured on Analog Channel B).
