Note that as the decaying curve for a RC discharging circuit is exponential, for all practical purposes, after five time constants the voltage across the capacitor’s plates is much less than 1% of its inital starting value, so the capacitor is considered to be fully discharged.
The discharge of the capacitor slows down. Eventually, the capacitor is fully discharged – the voltage across it is zero. This arrangement does not require a second switch, as the capacitor finishes uncharged, allowing the investigation to be repeated directly. The discharge behaviour is shown in the graphs that follow.
At 1 time constant ( 1T ) Vc = 0.37Vc. Therefore, Vc = 0.37 x 10V = 3.7V c) How long will it take for the capacitor to “fully discharge” itself, (equal to 5 time constants) 1 time constant ( 1T ) = 2.2 seconds.
As the capacitor discharges its current through the series resistor the stored energy inside the capacitor is extracted with the voltage Vc across the capacitor decaying to zero as shown below. As we saw in the previous tutorial, in a RC Discharging Circuit the time constant ( τ ) is still equal to the value of 63%.
That current charges the capacitor, and after about 0.1 s it will be fully charged, no more current will flow, and the LED will be off. The capacitor will have no way to discharge, except for its internal loss, which can require a lot of time. The next time you push the button, the capacitor is still charged, and no current flows.
The circuit opposite can be used to investigate the discharge behaviour of a capacitor. When switch S is closed, the capacitor is connected directly to the power supply. As there is virtually no resistance in the current path, the capacitor charges up almost instantly to the supply voltage.
