Any dielectric material can be used to separate the two metal plates inside a capacitor. This includes polymer, paper, glass or even air (although air is seldom used now).

Can an 2 farad capacitor still be used if the terminals were crossed at connection?
I Rather not think that you can buy 2 farad capacitor and no the terminals must follow polarity guidelines.
Why connect a 100 Ohm resistor to the two terminals of a capacitor If the voltmeter doesn't turn to zero would be better to use a larger resistor?
We can guess that the resistor is used for discharging the capacitor's plates. Generally we short the two terminals on a capacitor to discharge it fully. A resistor will take more time to do this than shorting-out the terminals: the higher the resistance, the longer the time that will be taken to discharge a capacitor fully.
What does 200WV 470uF mean on a capacitor?
200WV is the working voltage of the capacitor. This is the value that should not be exceeded between the two terminals. 470uF is the capacitive rating of the capacitor. It means 470 micro Farads, or 0.47 Farads.
How do you identify that capacitor is as Electrolytic capacitor?
Electrolytic capacitors look like little batteries. Any capacitor that looks like this will be electrolytic.Another AnswerElectrolytic capacitors are polarised, so their terminals are marked with positive and negative symbols.
Why is it important that the two capacitors must have their positive terminal toward the transistor?
A: It is not important what is important it that the capacitor has the correct polarity across its terminals otherwise it will not function correctly
What separates axon terminals?
The fluid filled space that separates axon terminals are called what
What is metallic film?
A metal film capacitor is an electrical part that holds energy electrostatically inside of an electric field. The capacitor has a dielectric which separates two electrical parts which are made out of thin film.

How can you use a 3 phase capacitor as a single phase capacitor?
Just use any two of the three terminals that are available, this will give you a single phase capacitor.
What will happen if two terminals of capacitor are shorted?
When the terminals of a capacitor are connected together, the capacitor will discharge, returning to a zero potential state. Capacitors resist voltage change, meaning that if the capacitor is in a circuit that has zero voltage potential, the capacitor will eventually achieve zero potential. If the capacitor is in a circuit that has a 5 volt potential, the capacitor will seek and attempt to maintain that 5 volt potential (provided that the capacitor is rated at 5 volts or more). In an AC circuit, the capacitor will tend to smooth out the sin wave of the current, resisting change in both directions. In a DC power supply circuit, a capacitor will tend to reduce the voltage "ripple", and if the circuit is designed properly, will provide a smooth DC voltage. Shorting the terminals of a capacitor is effectively what often happens in many circuits; it's not a problem.
How do you prevent shock by capacitors?
Discharge the capacitor, normally with a resistor accross the terminals (Calculated size)

Why it is usual practice to connect a capacitor between the power supply terminals of logic gates?
why did no one answer this qusetion
How do you change a bad capacitor in an air conditioner?
Locate the defective capacitor, short the terminals to ground to release any stored energy and prevent shock, remove the old capacitor then install the new capacitor wired as the old one was and secure it in the bracket that held the old one - done.
What do capcitors do?
In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. If you have read How Batteries Work, then you know that a battery has two terminals. Inside the battery, chemical reactions produce electrons on one terminal and absorb electrons on the other terminal. A capacitor is much simpler than a battery, as it can't produce new electrons -- it only stores them.In this article, we'll learn exactly what a capacitor is, what it does and how it's used in electronics. We'll also look at the history of the capacitor and how several people helped shape its progress.Inside the capacitor, the terminals connect to two metal platesseparated by a non-conducting substance, or dielectric. You can easily make a capacitor from two pieces of aluminum foil and a piece of paper. It won't be a particularly good capacitor in terms of its storage capacity, but it will work.
