In addition to the resistance of the transistor and the capacitor is also one of the most important parts in the electronics.
Capacitors should be used for all kinds of applications, and there are also a very large number of variants.
You have various types of capacitors, a simple capacitor, trim capacitor, a variable capacitor, an electrolytic capacitor electrolytic capacitor.
But in order not to run too far ahead.
The trimmer is an electronic circuit used once adjusting a capacitance value and a variable capacitor do you do against weather radios to tune.
Channels off A capacitor voltages can hold electrical charges.
We connect for example a 1000 uf micro farad capacitor to a 4.5 volt battery, our first little test we can if we remove the battery, and we keep a small screwdriver between the two terminals of the capacitor.
Then we will see a spark.
Join the capacitor to a voltage meter, then we can present even before the battery voltage measurement, although this tension with time is getting smaller.
A capacitor is blocking DC.
Forms for AC she possesses a so-called alternating current resistance, which is dependent on the capacitance value of the capacitor and of the frequency of the alternating voltage.
An air trimmer is a capacitor in high shortwave transmitters and receivers built.
This trimmer capacitor can be adjusted by twisting.
Of the so-called rotor plate pack at a desired capacitance value the drive that is the rotation of the rotor, you can do with a screwdriver.
The name mica foil trimmer or trimmer is derived from the fact that there is insulating, as dielectric, a thin sheet of plastic or mica is present between the rotor and stator.
Then there are also ceramic trimmers.
If insulation material is here how could it be otherwise used ceramic material, hence the name.
This type trimmers is preferably used in the reception area of radio and television sets.
Capacitors with small capacitance values are generally made in the form of ceramic capacitors.
Capacitors with large capacitance values are usually structured as capacitors, thus can capacitance values between 1 micro farad and 10,000 micro farad be realized.
Capacitors that high tensions could include 350 to 285 volts are also known for their large size, Cup capacitors called in as a Cup capacitors can be three separate capacitors are built.
Another important fact is that capacitors must be connected to a voltage source.
With the correct polarity the case itself is the negative terminal.
When a wound capacitor, the terminals marked with a + and -.
Normal capacitors may be connected.
On a random manner Pooled capacitors capacitors should not be connected.
To an alternating Exception is the situation where one uses a bias.
Another group called tantalum capacitors are capacitors.
These are miniature capacitors for small operating voltages.
And then there is the suppression capacitor.
These are used in motors or switches.
Cause for their spark interference to radio and or television.
THE ELECTRONIC ENGINEER NEED A CAPACITOR FOR:
AC Voltages To Close Shortly.
To Maintain Equal Voltages.
Block Equal Voltages in A Circuit.
Together With A Coil To Form A Resonant Circuit.
To Let AC Voltages in A Circuit Through.
To Build Links Between Two Amplifier Stages.
For Rectification Disturbing to Filter AC Voltages Away.
By Measuring Voltage Discharge Of A Capacitor Times.
With Resistance To Build Circuitry For Certain Frequencies.
