Imagine building a circuit using a perfect insulator (a device of infinite resistance, which allows no current flow) in place of the carbon resistor
a. Would the plot of the data be a straight line?
b. If yes, what would the slope of that line be? If no, what shape would the line be?

Explain in words why the circuit in figure 6 charges the capacitor, while the circuit in figure 7 discharges the capacitor. Remember, current only flows in closed loops!
2. How can a linear fit be used to measure the capacitance C for both charging and discharging a capacitor given the capacitor voltage V(t) at different times? Take a natural logarithm of both sides of the voltage equations V(t) (Refer to Graphical Presentation of Exponential Decay Section).

For the Electrical Circuit shown, calculate the current running through
each resistor . You will need to sketch and/or label the resistors so I can interpret your
results. Show the voltage drop across each resistor, also.
This requires consideration of a parallel and series resistors together. Solve for the overall
resistance of the parallel resistors, then put it in series with the other. Eventually solve for
the current in each of the parallel resistors.
