Capacitors are characterized by two values: their voltage, exceeding which will damage the capacitor (sometimes leading to a violent explosion), and their capacitance, as the name suggests.
The voltage is expressed in volts. The capacitance is expressed in Farads. One (1) Farad is an amount of charge that makes the voltage across the capacitor terminals to rise by 1 Volt. If a 10mA current flows into the capacitor and it causes the capacitor's voltage to rise by 1V every second, the capacitor's capacitance is 10 milifarads.
1 Farad is a lot of charge, so for most applications, submultiples (microfarads and milifarads, mostly) are commonly used.
A curious note: the more voltage a capacitor can handle, the (usually) bigger the size of it. At low voltages and low capacitance, the capacitance doesn't influence the size that much, though.

Reactance in inductors and capacitors is expressed in which unit of measure?
ohm
Whether film capacitors can be replaced with ceramic or mica capacitor?
Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing. However, mica capacitors can be replaced with ceramic capacitors in general.
Why do capacitors leak?
Mostly the leakage of capacitors is due to the resistor.
How many capacitors are use in a circuit?
Capacitors store charge. There are many applications for their use. There is no set amount of capacitors in a circuit since it is application dependent.
How do you measure capacitance?
A capacitance meter is a piece of electronic test equipment used to measure capacitors. Depending on the sophistication of the meter, it may simply display the capacitance or it may also measure a number of other parameters such as leakage, equivalent series resistance, and inductance.
What is an nF?
If its capacitors you are talking about, it stands for nanoFarad and it is a unit of measure.
What is the unit of measure of capacitor?
Capacitors are measured in Farads or microfarads.
Reactance in inductors and capacitors is expressed in which unit of measure?
ohm
Are capacitors polarity sensitive?
The capacitors those are polarity sensitive are called electrolytic and tantalum capacitors. These capacitors are labeled as positive and negative.
How are capacitors rated?
Capacitors are rated in Microfarads
What is the difference between electrolytic capacitors and normal capacitors?
because normal capacitors does not have any polaririties.
Whether film capacitors can be replaced with ceramic or mica capacitor?
Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing. However, mica capacitors can be replaced with ceramic capacitors in general.
How can you stop Television from humming?
Replaced capacitors that are no lomger capacitors.
What is the population of Nokian Capacitors?
Nokian Capacitors's population is 290.
When was Nokian Capacitors created?
Nokian Capacitors was created in 1957.
Why do capacitors leak?
Mostly the leakage of capacitors is due to the resistor.
