Chapter 4:
Top Skills 3: Basic Electronics
Synopsis
With a little bit of trained knowledge, it is not that difficult to understand the basics of electronics and their connective uses. Having a basic knowledge of how circuitry boards work will help you to have a better picture of the overall electronics experience. All electronics people should know the various connotations involved in this line, before actually attempting to handle any electric related problems.
Basic Electronics
The following are some elements connected to the electronics theme:
- There are basically two types of electrical signals, which are AC and DC. With the DC style, the electricity flows in one direction between the power and the ground where there is always a positive source of voltage and ground source of voltage. The electricity is defined as having a voltage and a current rating which are then depicted as Amps.
- The circuit is a complete and closed path through which the electric current flows between power and ground, thus an open circuit would work in the opposite way of where the flow of electricity is broken.
- The resistance feature is an important part of the circuitry as it ensures the electrical flow is being channeled and used, otherwise a short circuit will occur. Short circuits occurring are bad as they can cause severe damage to the electrical item and also cause fires and explosions. Therefore, ensuring the electrical flow is never wired directly to the ground is very important.
- Understanding and choosing between series and parallel is essential in deciding its appropriateness for the intended electoral item.
- Resistors are in place to help reduce and balance the flow of electricity. They come with different wattage ratings, which are low voltage DC circuits of ¼ watt resistors.
- Capacitors are components that store the electricity and then discharge it into the circuit when there is a disturbance which results in a drop in electricity.
- Diodes are components which are polarized and they only allow electrical current flows in one direction. This is useful when there is a need to check for a flow in the wrong direction.
