Pre-lab Exercise #5. Determine an expression for the capacitor voltage for the circuit in Fig. 3

valid for t> 0 given R = 10k2, C = 0.1μF, v(0) = v= 1V, and V, V, -1V.

v(t) =

Write a MATLAB script file to compute the capacitor voltage v(t) by calculating the voltage

from time t= 0 to t= 5ms in increments of 1 ms. Use the results to complete the Calculated

column of Table 2. Include a copy of the script file and output in your report.
