Voltage Divider And Theories On Basic Electronics

By Jason Taylor


The first thine which you should know in building electrical circuits for an electrical device are basic theories in electronics. Know the different components used and how to connect them properly to each other. Then study how to read and make schematic diagrams which are graphical representations of an electrical circuit using symbols and images.

It is important to do so when you want to make a certain device but are confused still with some parts concerning the process. Voltage divider is an example of an advanced topic which the produced output is only a portion of what its input is. But first, learn or review the theories on basic electronics and understand the advance stuffs better.

Begin with identifying the types of electricity such as AC or alternating current and DC or direct current. The direction which electrical signal flows on AC is constantly reversing or alternating with the reversal rate measured in Herts. Meanwhile the flow in DC is one direction to ground from power source and found commonly with batteries.

A circuit is closed when electric current is being allowed passage through a path to ground from power source which indicates a functioning device normally. While the open one has broken the path and prevents movement when a machine is turned off. This is done using a switch so you can alternate between them rather than removing its source.

Components creates resistance if current pass through from a positive voltage to a ground and a short circuit happens when these two are connected directly. Avoid this direct connections because they would result in breaking, overheating, explosion or fire. Putting only a switch between them is not enough and other parts are needed for additional resistance.

Wiring things together can be done in two ways which are called series and parallel with the former indicating that all components are wired after the other. While the latter indicates that the parts are wired next to each other and which makes electricity pass them simultaneously. Both ways could be used in building your own circuits.

Adding resistance into circuits is done with resistors and they reduce current flow and are also available in a variety of values measured with ohms. They have wattage ratings also and their value is indicated by colored bands around their body. You could learn reading these bands or look up for graphs that helps in calculating their values.

Capacitors are components which stores electricity then when it drops, discharges them and Farads is used to measure them with common units being picofarad, microfarad, and nanofarad. The capacitor types most used commonly are ceramic disc as well as electrolytic. The former is non polarized while the latter is polarized needing one leg to properly connect with the corresponding one.

Diodes are components which are polarized allowing passage for currents in one direction and will cause voltage drop. One side of it is called cathode that connects to power while the other one is anode. These are just a few samples of some basic theories you shall learn for making electrical devices.
