I do not understand how to even setup this lab based on the information provided. Willing to venmo anyone who is willing to complete labs for me.
Lab 7 RC circuits: rapid decay Before attempting the assignment read the description of Experiment 7 in the lab manual concentration on the theory. This assignment is Part II, Rapid decay, only. 11 C Lab 7 RC rapid decay theory https://youtu.be/6 -59u16Fho 11 C Lab 7 RC rapid decay experiment https://youtu.be/QcoYUYB1-38 Experiment. An RC circuit was assembled according to the circuit diagram shown in Fig. 7.3 of the lab manual. A function generator with the output resistance of about 50 Ohms generating a square waive (f=100 Hz) served as a power supply. The resistor box (set for R=2000 Ohms) was connected in series with a capacitor (C=0.514 HF). A square-wave signal applied to the circuit was registered on Chl of the oscillator, whereas the signal across the capacitor - on Ch 2. (one of the ground wires were not connected because the two channels of the oscilloscope share a common ground) (Fig. 1). Fig.1. RC circuit setup. The oscilloscope settings were adjusted to better see several cycles of the square wave on Ch 1 (Fig.2). (In Fig. 2. VAR SWEEP is on to better visualize the signal; do not use Fig.2. for data processing). 2120B DUAL TRACE O Fig. 2. Square wave signal from the generator.Then the oscilloscope was adjusted to see at least one cycle on Ch 2 (Fig. 3). (Here also VAR SWEEP is adjusted to better visualize the signal; do not use Fig. 3 for data processing). Fig. 3. Signal across the capacitor. Signal from the capacitor consists of two parts that correspond to charging of the capacitor (ascending part of the curve; described by Eq. 7.5) and discharging of the capacitor (exponential decay; described by Eq. 7.4). Then the oscilloscope was adjusted to show only the exponential decay curve describing the discharging of the capacitor (Fig.4). One can see the settings that should be used for processing of the decay curve: Ch 2 is set to 1 V/div and 0.5 ms/div. (1 div is a size of the square on the screen; it is divided by 5 small ticks) BK PRECISION TIME BASE TIME/DIV CH 1 CHY - VOLT/DIV VOLT/DIV - Fig. 4.

Use this image for processing of the RC decay curve. In the photo the horizontal scale is at 0.5 ms/div and the vertical at 1 V/div. Please note that the origin is shifted by one tick to the right (1 tick=0.2 div*0.5ms/div=0.1 ms). . . . . 10- Fig. 5.

Analyze each experiment and prepare the report in the following format: Name/ Names: Date: Title: Lab Objective: Write a short paragraph, in your own words, stating the objective of the laboratory. Equipment: Provide a sketch of the setup of the major pieces of equipment and their arrangement. Experimental Procedure: Summarize in a sentence or brief paragraph procedures, techniques, or methods used during the lab. Data & Analysis Describe the experimental setup and how the decay constant was measured. From the decay curve, measure the time constant t, where tis time need for the signal to decrease e=2.718 times. To do this, first estimate the maximum voltage across the capacitor VC max. Then calculate Vc max/e, and find from the graph how much time is needed for the signal to change from VC max to VCmale. Compare the measured t with the theoretical value =RC. Measure the half-time, t1/, necessary for the voltage across the capacitor to fall from its maximum value VC max to one half of that value, VC max/2. Calculate t from t1/: T= t1/2/In(2), and compare it with the previously found value. Referring to the minimum voltage of the trace as 0 V, measure Ve(t) from the graph for t=0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, and 4 ms. Calculate Vc(t)/ VC max and In(Vc(t)/ VC max) for each of the measured values. Plot In(Vc(t)/ VC max) vs t, with t on the horizontal axis. Calculate the slope of this graph, and calculate T=-1/(slope), and compare it to the previously obtained value. Conclusions In a short paragraph, describe the essence of the physical phenomena studied in this lab and the results of those studies. TO 6:16 PM 4/12/2022 1
