it is a lab final exam if you can do it by 10:45am. I just need screenshots


PHYS 262 – Spring 21LAB FINAL (Proposed)May 5, 2021 Instructions: This lab final has two questions. Each one is a mini-lab. Complete each lab by following the instructions and answering the questions that are asked. You do not have to follow the lab documentation formations that you used during the semester. Just answer the questions and provide any screen shots that are requested. Save everything into a word document or a pdf and post the result to the dropbox in the class (NOT COMMUNITY) blackboard page where this lab final exam was posted for you. 1. OHM’S LAW. Use EveryCircuit to create a circuit with at least 2 resistors in parallel that will demonstrate the validity of Ohm’s Law. a. Write a VERY BRIEF abstract that states what Ohm’s law is, and how you will prove its validity with a test circuit. b. Build the circuit and take a screenshot of it. Copy the image to your word file. c. Take at least 4 data points with your circuit and present them in a well organized data table in your word document d. Plot that data in a properly labeled plot in your word document. e. Conclude with 2-3 sentences that explain why your data and plot prove the validity of Ohm’s law. 2. AC PHASE Use EveryCircuit to create a series AC circuit that includes 2 parallel capacitors that has the following parameters: R = 400 Ω, L = 200 mH, C1 = 0.010 µF and C2 = 0.015 µF. Make sure to include a ground, and that the components are connected in such a way that the signal generator and the resistor voltages (relative to ground) can be measured. Set the signal generator frequency to 2.38 kHz (sinusoidal). a.Take a snapshot of the circuit and copy the image to your word file. Label it appropriately. b.Connect the EveryCircuit oscilloscope so that you can see the generator voltage in 1 channel and the resistor voltage in the other channel. c.Start the circuit. Wait long enough that a few complete waveforms appear on the scope. d.Set the scope time scale so that you can see two or three complete waveforms. e.Pause the scope. Maximize the window and take a screen shot of your signals. Copy this image to your word file and label it appropriately. f.Measure the period on your circuit and compare with the period you expect from the generator frequency. Report your calculated and measured periods. Are they similar? Should they be? g.Measure the time shift between generator and resistor voltages and use it to find the phase angle φ1. h. Calculate the phase shift φ2 from the parameters that you used in the circuit (L, R, C and frequency) and compare to φ1. Report how φ1 compares to φ2. Are they similar? Should they be?

Ohm’s Law
Ohm’s law states the relationship between electric current and potential difference. Ohm’
s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature, remain constant.
V = IR,
where V is the voltage across the conductor
I is the current flowing through the conductor
R is the resistance provided by the conductor to the flow of current.
Ohm’s law holds true if the temperature and the other physical factors are constant. The rise in current, for example, raises the temperature of some materials. Consider a light bulb's filament, where the temperature increases with the increase in the current. In this case, Ohm's law is not valid.
We can verify the law by building a...
