Complete three problems with no video just an exaptation of one.
Problem 1:  
Consider the electric circuit below for cars:
A. Are the bulbs in parallel or series?  Explain why this is designed this way
B. What is the voltage of a car battery (use google)?
C. What is the voltage drop across the car bulbs?
D. Is the tank sensor in parallel or series with the fuel gauge?
E. Which of these two circuits can leave your car battery dead, why/explain?
F. What is the standard power used by a car light bulb?  Use Google.  How would you estimate the current through the bulb?
G. List two more items that use electricity in your car.  Draw them in the same format as above: Battery, Earth, Load (item).  For each circut explain if you should include the ignition or not.
Problem 2
A. Use Excel (or Google Sheets)l to make a plot of a sin wave with the following properties.  Amplitude of 10, angular frequency of 6.  Plot this from 0 to 2*Pi.
B. Illustrate what it means to make a phase shift of your wave.  How did you change your Excel file?
C. Now make wave of amplitude 5 and angular frequency 1.  Plot this from 0 to 2*Pi
D. Add the two waves and show the result.
E. Use this website: https://www.compadre.org/osp/EJSS/4487/272.htm Explain in your own words what Fourier Analysis?  How does it explain why a guitar and trumpet can play the same notes and yet sound different?
F. In O-Chem lab you likely have used an FTIR spectra.  What does this acronym stand for?
G. Why do you think they use the term Fourier Transform to describe this tool?
Problem 3
Just answer the highlighted parts of this question
In this problem you will need to construct a pendulum and make a video to answer the following questions.  You will have to explain some of your results on video.
A. Write an equation for the oscillations.  What is the relationship between the amplitude and period?  How can you demonstrate this with an experiment?  Show this on a video.
B. What is the equation for a period of the pendulum.  How can you use this equation to measure the gravitational constant g?  Do the experiment and show your results.
C. The equation above only works for “small angles.”  Can you demonstrate that the equation for a period works well for small angles (below 25 degrees, but doesn’t work well for large angles?)  Demonstrate this with an explanation on a video.
Problem 4
In the figure below is shown part of the circuit that is used to model the cell membrane of an electrically excitable cell. While the actual model includes variable resistors, let’s analyze the simplest example of this circuit: take the batteries to be identical and ideal and taking the resistors to be identical and Ohmic. The capacitor plates (inside the plastic shell shown) correspond to the inside and outside of the membrane.
 
Suppose the batteries each are labeled with a voltage V0 and the resistors each have a resistance R. Where asked for currents or voltages express your answers in terms of V0 and R.
 
A. The batteries are not connected with the same orientation. When the network reaches a steady state and the capacitor is charged is there any current through the batteries and resistors? Explain briefly why you think so.
 
B. There is no current through a charged capacitor.  Find the voltage drop across each resistor. If you think that there is current, find the current through and voltage drop across each resistor.
 
C. Is there a voltage difference across the plates of the capacitor? If so, find it. If not, explain why there is none.

Problem 1
a. Both the bulbs are in parallel. They are connected this way so that both of them receive the same voltage. If
they are connected in series, then their voltage will be reduced by half and hence they will not work.
. Voltage of a car battery is 12.8 V.
c. Since both the bulbs are connected in parallel, so voltage drop across the bulbs is same as that of battery i.e. 12.8 V
d. Tank Sensor is in series of the fuel gauge as both of them will have the same cu
ent.
e. The second circuit with the two bulbs connected will leave our battery dead as there is no switch connected in the circuit. So, battery cu
ent will flow always and drain the battery whereas the first circuit have the ignition switch connected to it.
f. Standard power of a car light bulb is 55 W. Cu
ent through the bulb = Powe
Voltage = 55/12.8 = 4.3 A
g. Two other items which uses car battery are Car horn and Brake light. These are not required to be connected to the ignition but to be connected to the respective buttons.
Problem 2
a.
. Phase shift of a sinusoidal wave means to horizontally shift the sinusoidal wave along the time axis by the given shifted angle.
c.
d.
e.
Fourier series is defined as the representation of...
