To comprehend the goal of electronic components, it is very important to first have a grasp on the basic principles of electronics. Electronics is the study of the way the flow of electrons could be manipulated to in a certain direction and at a particular strength to be able to cause desired reactions on mechanical devices. This process has been utilized for a long time to boost the efficiency of the entire world around us and how exactly we relate with it. Although electronics has advanced tremendously, the basic components used in the field have stayed the same; each small piece has its purpose and can't be overlooked.
A number of the main electronic components are:
Resistors - A resistor is a component that's used to resist the flow of electricity, allowing only the specified total flow through. These can be hugely useful in allowing a control knob to work, since the setting chosen will relate to the resistance level. Resistor strength is measured in OHMs, but since there is generally a high resistance level, the prefixes kilo(k) and Mega(M) are used to delineate the strength. The strength is displayed on the component using a group of colors that all relate to lots between 1 and 9. Three colors displayed on the resistor could be added together to determine the strength: The very first two colors determine the initial and second digits, while the next provides the amount of zeros.
Capacitors - Capacitors store a certain amount of electricity that the device can use when needed. Many devices demand a quick burst of energy that may not be performed with out a backup energy source Temperature Sensors. The capacitor strength is measured in farads(F) and uses the prefixes micro (millionth), nano (thousand-millionth), and pico (million-millionth) to measure its strength. These components are extremely small, so just like the resistors, the capacitors are color coded to produce the strength.
Diodes and Transistors - These both handle modifying the flow of the electrical current. Diodes, an example of which is a Light Emitting Diode (LED), serve as the "train tracks" for the existing, and can flow in a single specific direction and maintain a particular strength. Transistors, which can either be NPN or PNP, are used to control or amplify the existing to the specified strength. Both diodes and transistors are integral electrical components, and allow electronics to perform smoothly.
These components might be small, but without them practically every computer we use would be worthless. If you are new to electronics, it is way better to leave repairs to a professional, but with only a little experience, it's not far-fetched to be able to start gadgets and replace or modify these parts. It could be overwhelming initially, but learning the basic principles of electronics is similar to learning how to ride a cycle: Once you have the method perfected, you'll always remember it.
