Derivation of the capacitance of Capacitor. The capacitance of a capacitor can be calculated using the following formula: Capacitance (C) = Charge (Q) / Voltage (V) Where C is the capacitance in farads (F), Q is the charge in coulombs (C), and V is the voltage in volts (V).
For large capacitors, the capacitance value and voltage rating are usually printed directly on the case. Some capacitors use "MFD" which stands for "microfarads". While a capacitor color code exists, rather like the resistor color code, it has generally fallen out of favor. For smaller capacitors a numeric code is used that echoes the

Supercapacitors, also known as ultra-capacitors, are polar capacitors with a large capacitance but a low voltage rating. Supercapacitors have low voltage ratings of about 2.5–2.7 V, and their capacitance may range from 100 to 12,000 F. Supercapacitor is an energy storage device that bridges a capacitor and a battery. These capacitors have a higher charging
