Fit a line to each plot and determine it’s slope. What physical quantity does this slope correspond to and is its value what you expect? Refer to the “2CL Curve Fitting in MATLAB” guide for instructions on fitting. Since you’ll be doing a linear fit, use the example function(s): modelfun 1 = @( p, x ) p (1) . * x ; modelfun 2 = @( p, x ) p (1) . * x + p (2); Which would be more appropriate? What if there is some systematic error? Try both and discuss the results. 8.3 Charge and Energy Now that you’ve verified the capacitance of the components by measuring the time constant let’s consider some other aspects of the capacitor. Determine how much charge is being stored in the capacitor when fully charged and the current in the circuit ( I ( t )). Consider the following: 8

How is the voltage across the capacitor and it’s capacitance related to the charge it stores (assuming a constant capacitance)? From your fit of V ( t ) how would you determine Q ( t ) ? How is Q ( t ) related to I ( t ) ? Once fully charged how much energy is stored in the capacitor? 9

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
