Capacitor Charging and Discharging

You can "reset" the capacitor back to a voltage of zero by shorting across its terminals with a piece of wire. The "time constant" (τ) of a resistor capacitor circuit is calculated by taking the circuit resistance and multiplying it by the circuit capacitance. For a 1 kΩ resistor and a 1000 µF capacitor, the time constant should be 1 second.
