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 essential when there is a particular device you want to make but is still confused with some parts of the process. This might be something a little advance such as voltage divider which produces an output that is a portion of its input. But learn or review first the theories in basic electronics to understand better the more advanced 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 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.
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.
Resistors are used to add resistance into circuits and reducing their current flow with ohms used in measuring its different values. They have also wattage ratings and the colored bands surrounding their body indicates their resistance value. You can learn these colored bands or search for graphs which helps calculate their values instead.
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 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.
