Electronics
Electronics deal with circuits and electric components that are used to complete simple tasks which in term are applied in a computer to accomplish difficult calculations.
There are some materials that are categorized as conductors, insulators and semiconductors. Conductor is anything that easily allow electrical flow to run through it. Copper wire and water are an example of a conductor. Opposite to the conductor, insulator prevents electricity from traveling trough it. Plastic and rubber are good insulators. Semiconductors have the qualities of both, conductor and insulator. It has an ability called "doping" that allows it to change conductivity. Silicon is a typical example of a semiconductor.
Beside conductors, insulators and semiconductors there are other electronic components that are used inside of electric circuit but serve different purpose.
The circuits are used to power up certain devices by sending voltage through it. The circuits functionality is determined by its structure. There are two types of circuits. Series and Parallel. In both resistance is measured in Ω (Ohms) and is labeled as R. Current is measured in A (Amps) and is labeled with I and voltage is measured in V (Volts) and has a label of V.
Series: In a series circuit the resistors are located in a sequence one by one. The battery provides voltage gain and there is voltage drop across each resistor. The current is the same in each spot of the circuit. Any time that the resistors or loads are located as shown in Figure 1 the circuit is considered to be in series. Parallel:
in a parallel circuit the resistors are in a set of circuits that are connected to the same battery. The voltage is the same across each resistor, however, the current is split among the resistors. Any time that the resistors or loads are located as shown in Figure 2 the circuit is considered to be in parallel. |
