The capacitor will charge rapidly at a rate determined by the maximum current of your power supply, the ESR of the capacitor, and any parasitic L/R, whereupon it will act as an open circuit, with no further current flow. Depending on your power supply, you might trip the overcurrent protection.
You will probably see a spark if you are connecting the capacitor to a live supply. The capacitor will charge rapidly at a rate determined by the maximum current of your power supply, the ESR of the capacitor, and any parasitic L/R, whereupon it will act as an open circuit, with no further current flow.
When capacitors in series are connected to a voltage supply: because the applied potential difference is shared by the capacitors, the total charge stored is less than the charge that would be stored by any one of the capacitors connected individually to the voltage supply. The effect of adding capacitors in series is to reduce the capacitance.
Energy is needed from a power supply or other source to charge a capacitor. A charged capacitor can supply the energy needed to maintain the memory in a calculator or the current in a circuit when the supply voltage is too low. The amount of energy stored in a capacitor depends on:
What is not shown is that the input must contain a diode or similar component, so if the input voltage is lower than the capacitor plate voltage then the capacitor does not discharge back into the power supply. (I'm 20 years past A-levels and still find the marking schemes obtuse, they're simplified beyond the point of understanding)
Too high or too low capacitance values may make the DC supply unstable. It depends on the voltage ratings of the capacitor and the power supply - and how much current the power supply can deliver. If the the power supply voltage is higher than the rated voltage of the capacitor, then the capacitor will be damaged.
