Record the resonant frequency below your Data Table. Enter a frequency of 300 Hz so you can see what an oval looks like before dialing in the resonant frequency to the nearest 1 Hz. Any phase difference will cause a half-oval trace. When the two inputs are in phase, the Scope display between VA and VR will show a diagonal line. Trace of Output Voltage, switch the Scope display to X-Y mode: To do this, make the scope display Voltage, Ch A (VR)vs. To check whether the trace of voltage from Channel A is in phase with the Make fine adjustments to the frequency until the trace of voltage from Channel A is in phase with the trace of Output Voltage. Look at the Data Table and determine approximately the resonant frequency (where voltage across the resistor reaches a maximum and the output voltage and resistor voltage are in phase). Increase the frequency by 10 Hz and repeat the process until 320 Hz is reached. Measure VR at its peak and record in a table like the one below: f (Hz) VR (V) I (A) 10 20 вЂ¦ 320 6. Make sure the color of the Smart Tool is the same as VR.

Use the button (Show data coordinates) to change the cursor to a crosshair. Click Monitor to begin monitoring data and adjust the scope settings so two clear sinusoidal traces are visible. Click on Continuous Mode and select Fast Monitor Mode.

Set the signal generator for Output 1 to a frequency of 10 Hz and an Amplitude of 3.0 V and turn the output On. Click on the Signal Generator tool in the vertical toolbar on the left. Phase relationship between VA and VR are the same as the phase relationship between VA and I. This also allows us to see the phase relationship between VA and I since the Knowing the resistance voltage allows us to find the current in the resistor, since I = The right and left vertical axes can be adjusted independently of each other. To add a second voltage display you will need to click on the button (Add new y-axis to slope display). Create a Scope display that shows the applied (output) voltage VA (Output Voltage, Ch01) and the resistance voltage VR (Voltage, ChA) vs. Make sure the red plug corresponds to the вЂњhotвЂќ side of the circuit. Attach the voltage sensor across the resistor. The hot (red) plug should connect with proper polarity as illustrated below.ДЈ. For the voltage source, connect the RLC circuit to the hot and ground Output 1 jacks on the interface box. Use two banana plug leads to create the following circuit using the RLC circuit board. Click on Output 1 and choose Output Voltage-Current Sensor.

Run PASCO Capstone and configure the software so it knows a voltage sensor is in Channel A. Plug the voltage sensor into Analog Channel A. Acquire a voltage sensor and an RLC circuit. Objective: To study resonance in an RLC circuit by examining the current through the circuit as a function of the frequency of the applied voltage.
