8.4: Transient Response of RC Circuits
This, in turn, means that the rate of capacitor voltage increase begins to slow. As the capacitor voltage continues to increase, less voltage is available for the resistor, causing further reductions in current, and a further slowing of the rate of capacitor voltage change. Eventually, the capacitor voltage will be nearly equal to the source ...
Capacitor Charging
Below is a typical circuit for charging a capacitor. To charge a capacitor, a power source must be connected to the capacitor to supply it with the voltage it needs to charge up. A resistor is placed in series with the capacitor to limit the amount of current that goes to the capacitor. This is a safety measure so that dangerous levels of ...
