i've got this circuit:

im after the time constant which i know as
tau = RC.
in another example in tutorials it shows a similar circuit but the capacitor is around the 200 ohm resistor and hte 800ohm resistor taking the place of the capacitor.
afterwards it works out the thevenin of the circuit.
im guessing i have to do that here? but im not sure where to start.
