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.
Start by identifying the two kinds of electricity that are direct current and alternating current which are also known as DC and AC respectively. In AC, the direction where the electrical signal flows is alternating or reversing constantly with Hertz used to measure the reversal rate. In DC though, the movement is one directional from power source, commonly batteries, into the ground.
A closed circuit is when the electric current is allowed to pass through a path from power source to ground which normally indicates a device is functioning. While an open one breaks this path and will prevent the movement just like in turning off a machine. This is done with a switch so you could alternate between them instead of removing the source.
Components create resistance when current pass through them from positive voltage to ground and if these two are directly connected, it would cause a short circuit. This direct connection will result in explosion, fire, breaking or overheating which must be avoided. A switch would not add resistance so simply putting one without other parts is not advisable still.
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 that are polarized allowing one direction of passage for currents and causes a voltage drop as well. The side called cathode connects to the power and the opposite side is called anode. These are samples only of a few basic theories so research more about them.
