Chapter Questions
Judging on the basis of your experimental results, under what conditions are the charging times of different $R C$ circuits the same?
In the form $V=V_{\mathrm{o}}\left(1-e^{-\mathrm{s} / \tau}\right)$, the $\tau=R C$ in the exponential must have units of time. (Why?) Show that this is the case.
In the form $V=V_{0}\left(1-e^{-t / \tau}\right)$, the $\tau=R C$ in the exponential must have units of time. (Why?) Show that this is the case.
How could the value of an unknown capacitance be determined using the experimental procedures? Show explicitly by assuming a value for an experimentally determined time constant.
