Question
Assemble the circuit in Figure 1 with R = 470kO, C = 47µF and source voltage about
5V. Place the switch in the charge position and wait for the capacitor to charge.
a. Calculate the time constant, t for the circuit:
Tcalculated =
b. Return the switch to the discharge position and wait for the capacitor to
fully discharge. Move the switch to the charge position and using the
stopwatch, measure the time it takes for the capacitor voltage to reach
63.2% of its maximum capacitor voltage, Ve .This is the measured time
constant.

Hold the switch in the charge position until the capacitor voltage
stabilizes at maximum capacitor voltage, Vc. Now moves the switch to
the discharge position and measure the time it takes for the voltage to
drop to 36.8% of its maximum capacitor voltage, Vc.
