A capacitor with capacitance C 0 , after having been connected to a battery with emf
Question:
A capacitor with capacitance C0, after having been connected to a battery with emf ξ0 for a long time, is discharged through a 200 000Ω resistor at time t = 0. The potential difference across the capacitor is measured as a function of time for a brief time interval; the results are recorded below.
(a) Write an equation that describes the potential difference across the capacitor as a function of time. Enter the data into your calculator and have the calculator perform a linear regression fit of in VC versus t. From the parameters of the fit, determine
(b) The emf ξ0 of the battery and
(c) The time constant τ for the circuit.
(d) Finally, determine the value of capacitance C0.
