Questions
1.
Use Equation (7) to calculate the voltage across the capacitor at time $t = RC$. This yields
$e^{-1}$. Use your experimental value of $V_c$. Now compare to your data table. Which of your
measured data points comes closest to this value? (Note the voltage and time)
2.
Could we have ignored the $R_g = 50 \Omega$ resistance in the function generator? Use percent
difference with $R_g$ as the accepted value, $R$ as the experimental value. Assume that a
systematic error from this source can be ignored if it is less than 5%.
3.
From $RC = \frac{1}{ln(V_o/V_c)}$, calculate the time constant $RC$ for the circuit by using:
$RC = slope$
4.
Which combination would have the largest equivalent capacitance, two 0.10µF capacitors in
parallel or two in series? Show your calculations.
