subject: map about electronic distributors 465 [print this page] Electronic digital elements form components of electric circuitry, and are employed or manufactured in the field of electronics, which is the study of electrical products applied for controlling electrically charged particles or the circulation of electrons to execute any electric operation. Some of the most popular electronic parts are as follows:
Resistor: A resistor resists electric current, and the resistance is measured in ohms. Colours on the body of the resistor are a code for the value. Diverse colors represent the numbers from to 9. In a variable resistor, resistance can be varied by moving a knob or slider. A variable resistor is employed to manage volume in numerous devices.
Capacitor: This is measured in farads. A capacitor is employed for storing electrical charges that can be released upon demand. Capacitors can be of various sorts - electrolyte and ceramic disc are two of them.
Diode: A semiconductor device, diodes permit current to circulation in 1 course only.
Modest, inexpensive and lasting, light emitting diodes (LEDs) are exclusive diodes that give out light and permit recent to flow in a single path.
NPN bipolar transistor: Utilized for current manage, they can amplify currents with a little volume of heat dissipation and really small spatial waste.
PNP bipolar transistor: Its functions are the identical as NPN, but construction is a bit
different.
Crystal: When a voltage is applied, crystals can accurately vibrate a specific frequency.
Integrated circuit: Getting circuits etched into it, an integrated circuit is a semiconductor wafer that can hold capacitors, resistors, transistors, and so forth. in a huge quantity. By making it possible for the chips to have millions of transistors, integrated circuits are capable of saving space.
Triac: A dual silicon controlled rectifier (SCR), triac is used to handle alternating recent (AC). Mainly employed in dimmers and touch lamps, it controls the amount of electrical energy reaching an appliance.
Tapped secondary transformer: Employed for transforming voltages, a plug-in transformer, the wall kind, adjustments 120 volts AC into about 12 volts DC for tiny appliance requirements. In a tapped secondary transformer, the secondary winding of the transformer is connected to a wire so that it can be employed for numerous voltages, or much more present.
Speaker: A speaker converts electric energy into sound energy. Read more: electronic distributors
