What is Capacitor
Ceramic Capacitors are also called "Disc Capacitors." A code of 3 Digit is generally printed on the body of this type of capacitors to tell their capacitance in pico-farads. The first two digits represent the value of the capacitor and the third digit represents the number of zeros to be added. 2. Electrolytic Capacitor
Capacitor
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic component with two terminals.

How to Interpret Capacitor Markings
The above image shows a Mylar film capacitor. The top "683" marking indicates the capacitance value, which is 68,000 picofarads (pF). To get this value, you multiply the leading digits (68 in this case) by 10 raised to the power of the last digit (3), and the result is the capacitance in picofarads (in this case, we get 68×10 3 pF). There are three exceptions for the …
voltage
The initial voltage across the capacitor would be 0V (uncharged). The initial current would be limited by the resistance (R) and the supply voltage (10V) just like any other RC circuit, (I = 10/R amps) but as C is infinitely large (infinite time constant) the voltage across its plates will never rise and remain at 0V. The circuit will effectively act as a voltage source (10V) …

Capacitors
The capacitance of a capacitor -- how many farads it has -- depends on how it''s constructed. More capacitance requires a larger capacitor. Plates with more overlapping surface area provide more capacitance, while more distance between the plates means less capacitance. The material of the dielectric even has an effect on how many farads a cap has.
