    Determine the time constant of the natural response of the RC circuit by means of using thevenin's principal. Evaluate the resistance seen at the terminals of the given capacitor. A simple procedure for finding the time constant of the RC circuit you posted ( fed by a constant source) is:
    1. short the power source to ground.
    2. open the current source
    Therefore, you have a thevenin's equivalent resistance equal to 1. By doing the math, RC equals 1. Remember a one time constant......
