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 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.
When current pass through components, they create resistance to ground from positive voltage and if these are directly connected, this would cause the circuit to be shorted. This direct connection would result in fire, breaking, overheating or explosion which you must avoid. Putting switch would not provide additional resistance so other parts must be added.
Wiring things together could be done with two ways that are called series as well as parallel and the former indicating that every component is wired after each one. While the latter would indicate that the parts were wired next to the other which makes electricity simultaneously pass them. Both ways can be used together when you build 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.
