The first thing you must know when you build an electrical device with your own circuits are theories on basic electronics. Find out the various components used for them and the ways of properly connecting them with each other. Study also how to create and read a schematic diagram which graphically represents an electrical circuit with 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.
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.
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.
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.
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.
