How do capacitors get charged?

When a capacitor is connected between the terminals of a power supply (or cell) electrons are forced off of one of the capacitor’s plates and forced onto the opposite plate through the power supply.

Due to the action of the power supply which causes a current to flow electrons are forced off of the positive plate (hence there is a deficiency of negative charge and it gains an overall positive charge). Electrons are simultaneously forced onto the negative plate by the power supply (accumulation of negative charges hence it gains overall negative charge).
