Capacitance, Charging and Discharging of a Capacitor
The charging voltage across the capacitor is equal to the supply voltage when the capacitor is fully charged i.e. VS = VC = 12V. When the capacitor is fully charged means that the capacitor maintains the constant voltage charge even if the supply voltage is disconnected from the circuit.
Capacitor Voltage
When charging a capacitor using a constant voltage source V o, the voltage increases exponentially with time: [4] V = V o [ 1 − exp ( − t R S C ) ] where R S is the total series …
Capacitor Charging and Discharging Equation and RC Time Constant
It takes 5 times constant to charge or discharge a capacitor even if it is already somewhat charged. The capacitor voltage exponentially rises to source voltage where current exponentially decays down to zero in the charging phase. As the switch closes, the charging current causes a high surge current which can only be limited by the …

Capacitors Physics A-Level
The time constant. When a capacitor is charging or discharging, the amount of charge on the capacitor changes exponentially. The graphs in the diagram show how the charge on a capacitor changes with time when it is charging and discharging. Graphs showing the change of voltage with time are the same shape.
21.6 DC Circuits Containing Resistors and Capacitors
where (the Greek letter tau) is called the time constant for an circuit. As noted before, a small resistance allows the capacitor to charge faster. This is reasonable, since a larger current flows through a smaller resistance. It is also reasonable that the smaller the capacitor, the less time needed to charge it.Both factors are contained in .
8.1 Capacitors and Capacitance – University Physics Volume 2
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage V across their plates. The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates. In other words, …
