When a capacitor is connected to a DC voltage source, it begins the process of acquiring a charge and builds up voltage across the capacitor. Once the capacitor has acquired enough charge, current starts flowing and the capacitor voltage approaches the value of the DC source voltage.
Charging a capacitor is very simple. A capacitor is charged by connecting it to a DC voltage source. This may be a battery or a DC power supply. Once the capacitor is connected to the DC voltage source, it will charge up to the voltage that the DC voltage source is outputting.
Hence, a fully charged capacitor appears as an open circuit to dc. Consider an uncharged capacitor of capacitance C connected across a battery of V volts (D.C.) through a series resistor R to limit the charging current within a safe limit. When the switch S is closed, a charging current flows in the circuit and the capacitor starts to charge.
A capacitor is charged by connecting it to a DC voltage source. This may be a battery or a DC power supply. Once the capacitor is connected to the DC voltage source, it will charge up to the voltage that the DC voltage source is outputting. So, if a capacitor is connected to a 9-volt battery, it will charge up to 9 volts.
Once the capacitor is connected to the DC voltage source, it will charge up to the voltage that the DC voltage source is outputting. So, if a capacitor is connected to a 9-volt battery, it will charge up to 9 volts. If a capacitor is connected to a DC power supply outputting 15 volts, it will charge up to 15 volts.
When a DC voltage is applied across a capacitor, a charging current will flow until the capacitor is fully charged when the current is stopped. This charging process will take place in a very short time, a fraction of a second. Hence, a fully charged capacitor blocks the flow of DC current.
