If you want to understand how the capacitor works without reading theory and formulas – then build this circuit: You can use a 9V battery, a standard Light-Emitting Diode (LED), and a 1000 µF capacitor. The resistor value can be around 500-1000 ohms. Connect the battery, and you should see the LED turn on. Nothing special yet.
What makes capacitors special is their ability to store energy; they're like a fully charged electric battery. Caps, as we usually refer to them, have all sorts of critical applications in circuits. Common applications include local energy storage, voltage spike suppression, and complex signal filtering.
Tolerance - Capacitors also can't be made to have an exact, precise capacitance. Each cap will be rated for their nominal capacitance, but, depending on the type, the exact value might vary anywhere from ±1% to ±20% of the desired value. The most commonly used and produced capacitor out there is the ceramic capacitor.
More capacitance typically requires a larger capacitor. Maximum voltage - Each capacitor is rated for a maximum voltage that can be dropped across it. Some capacitors might be rated for 1.5V, others might be rated for 100V. Exceeding the maximum voltage will usually result in destroying the capacitor.
The output becomes the opposite of the input. So if the input is LOW, the output is HIGH. When the output is HIGH, the output voltage will start charging the capacitor so that it eventually also ends up HIGH. But when it does, the output will switch to being LOW.
If you need a polarized capacitor, you need something called an electrolytic capacitor. The most common types are Aluminium and Tantalum. Aluminum is the cheapest of the two. But if you need a smaller and more durable capacitor, you should choose the Tantalum type. If you need a non-polarized capacitor, the most common types are Ceramic and Film.

Electrometers have a high enough input impedance to show the voltage discharge from a 100 picofarad capacitor, but why bother since (1) you probably won''t be able to get your hands on one and (2) it sounds like you don''t know enough electronics theory to appreciate what you would be trying to measure.
