**Lab 3 Exercise**

Table 1 contains measured values of the voltage across a capacitor and a resistor wired in parallel. The initial 10 volts decays as current flows from the capacitor. The voltage is an exponential function of time.

where

RCis the time constant.

- Plot the voltage as a function of time on semi-log paper to achieve a straight line with a slope of -1/RC.
- Determine the time constant from the plot.
Recall

You can draw semi-log paper on linear graph paper using this data.
