As the capacitor plates have equal amounts of charge of the opposite sign, the total charge is actually zero. However, because the charges are separated they have energy and can do work when they are brought together. One farad is a very large value of capacitance.
A basic capacitor consists of two metal plates separated by some insulator called a dielectric. The ability of a capacitor to hold a charge is called capacitance. When battery terminals are connected across a capacitor, battery potential will move the charge and it will begin to accumulate on the plates of the capacitor.
The capacitors ability to store this electrical charge ( Q ) between its plates is proportional to the applied voltage, V for a capacitor of known capacitance in Farads. Note that capacitance C is ALWAYS positive and never negative. The greater the applied voltage the greater will be the charge stored on the plates of the capacitor.
A single charged plate does have a capacitance associated with it. Let's say we have a single plate that has a charge of +Q on it, and another plate with charge −Q is at an infinite distance away. Contrary to initial thoughts, the capacitance is not zero.
A single conductor also possess capacity to store charge. It may be treated as parallel plate capacitor, whose one plate is at infinity. If this doesn't help, comment on the part where you have problem. So a capacitor with single plate can run appliances (or transfer energy) like a double plate capacitor? Yes.
When a capacitor is charged, the amount of charge stored depends on: its capacitance: i.e. the greater the capacitance, the more charge is stored at a given voltage. KEY POINT - The capacitance of a capacitor, C, is defined as:
