Pasco capstone rc circuit lab generator#
Click Signal Generator at the bottom left. You will use this data to make a graph of current as a function of frequency. For various frequencies, read the current from the display you set up before. (Less resistance means more current around the resonant frequency, making the effect stand out better.) There is no other change in the circuit. Should V C lead or lag I? Is this what you see? PART THREE: Resonance You will see if a circuit s calculated resonant frequency matches the observed resonant frequency. Should V L lead or lag I? Is this what you see? c. Should V R lead or lag I? Is this what you see? b. (A typical tolerance when components like these are manufactured.) 2. Comment on whether your measured and computed values for the current and three voltages agree with each other if the measured values have a 10% uncertainty. Get the instructor s approval of your sketches before going on there are often problems. (I should still be the same.) Repeat for the last of the three. Keep the wires arranged the same way just unclip R and L and put them in each other s places. Next, switch the resistor with the inductor to set things up as in the center picture. Just sketch a sine wave without all the little spikes.) Be careful to show the phase difference between V and I accurately. Sketch the graphs in the little boxes on the answer sheet. Record the amplitudes of the voltage and current. Numbers on the left go with the voltage and those on the right go with the current. Another sine wave should appear, which probably looks like a horizontal line at the moment. In the toolbar at the top, click on (Add new y axis to scope display.) By the vertical axis which appears on the right, click. To include the current as well as the voltage in the computer display, a. Click Output 1 at the top right of the picture. Remove the red wire of the voltage sensor from Output 1 and connect it to the un-grounded end of the resistor as in the picture on the left. The number in the box will probably need to be around 10.2 V. Adjust the number in the signal generator s Amplitude box until the graph actually shows an amplitude of 10.0 V. Do a lot of stretching on the horizontal axis until the graph shows just one or two periods. Click on Signal Generator and set the frequency at Hz. Just remove the meter and otherwise it is the same circuit from part one. (Solve this problem mathematically.) Experimental Procedure. Find the impedance of the circuit, the current, and the potential difference across each of the three circuit elements: the capacitor, resistor and inductor.
Pasco capstone rc circuit lab series#
The same R = 500 Ω, L = 5.0 mh and C =.01 μf from part one will be placed inĢ series with a V max = 10.0 volt, 15,000 Hz emf.

A computer with current and voltage sensors displays the amplitude and phase of the voltage across each of these. A resistor, inductor and capacitor are connected in series across a signal generator. In an AC circuit, we wish to see if calculated and observed voltages match, and if the phases of the voltages are as predicted. In your conclusion, explain why this is different from what you read off the graph. at the top of the graph then move the Add more wires to output 1 to connect to a digital voltmeter set for AC volts. The best way to read the graph is to click on crosshairs to the top of a peak. Record the amplitude of the voltage, which may actually be a little less than the 10.0 V you put in the box. Change the scale of the graph as needed by dragging the numbers along the axes as in last week s lab.

Near the left of the toolbar at the top, click to stabilize the display. Click the arrow where it says Continuous Mode near the bottom left. In the column on the right, double click Scope, which is second from the top.

To have the computer display the voltage on channel A, a. Click Signal Generator again to get that out of the way. Set the frequency at 60 Hz and the amplitude at 10.0 V. (The button on the interface should turn blue.) Open PASCO Capstone. Connect the interface to the computer with the USB cable and turn them both on. The voltage sensor plugged into channel A will measure this output voltage and the computer will display it on a graph. A signal generator built into the interface provides the emf to run the circuit from Output 1. 1 Experiment 8: An AC Circuit PART ONE: AC Voltages.
