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.
Doing so is important when you like to make a particular device but still confused on some parts of this process. This may be something a bit advance for you like the voltage divider which the output produced is a portion only of its input. Before tackling that, learn first or review the basic theories in electronics to better understand the advance stuffs.
Start with identifying the two types of electricity which are alternating current or AC and direct current or DC. The direction that electrical signals flows in AC is reversing constantly or alternating and the reversal rate is measured in Hertz. The flow in DC though is one direction from power source to ground and commonly found with batteries.
Circuit is closed if the path allows the electric current to pass through from a power source into the ground which usually indicates the device is turned on. An open one on the other hand breaks the path and would prevent movement such as when turning off machines. A switch is used in doing this so removing the source is not necessary when alternating between them.
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.
There are two ways to wire things together which are classified as parallel and series with the latter indicating all components are being wired one after the other. Meanwhile, the latter indicates the parts are being wired next with each other and that makes electricity to pass them simultaneously. Using both ways when building circuits is possible.
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.
Components which stores electricity and discharges them when they drop are called capacitors and is measured with Farads commonly shown in units of nanofarad, picofarad and microfarad. The types of capacitors commonly used are electrolytic and ceramic disc. The latter being non polarized while the former is polarized requiring one leg to connect properly with either the ground or power.
Diodes are polarized components allowing current to pass through one direction and would cause a voltage drop. One of its side is called cathode which connects to power and the other is anode. These are just samples of the basic theories you must learn in making electrical devices.
