    Introduction to Basic Electronics

    Electronics is a branch of science that deals with how electrical energy is controlled, an energy in which electron plays a fundamental role. Majorly, electronics deal with electrical circuits that comprise active electrical components such as transistors, vacuum tubes, integrated circuits, and diodes. Besides, electronics are associated with interconnected technology and passive electrical components. Often, electronic devices are comprised of exclusive semiconductors that are supplemented by passive elements.

    Electronic knowledge is widely used in telecommunication, information processing, and signal processing. Interconnection of technologies such as electronic packaging technology, circuit board, and other communication infrastructure transform mixed components into complete circuit functionality and a regular working system. As a student studying electornics, it is important to note that this is due to the nonlinear behavior of active components and their ability to control electrons flow and amplifications of weak signals. Besides, the ability of electronic devices to act as switches enables digital information processing. At the college level, some of the most fundamental topics one will cover in the introduction to basics electronic will include circuit components such:

    Resistors

    Resistors are common electronic components and virtually exist in almost all circuits. The resistance value is given in ohms, with standard symbol ? or “R”. They are commonly available in values that range from 0.1 ohms to 10M ohms, and they are always marked using a standard color code.

    Capacitors

    Primarily capacitors are made up of two conductive plates separated by an insulator, often assembly is rolled up consisting many small plates each separated from other by a thin film of plastic to conserve space. A capacitor also exists whenever a circuit has more than zero components such that any two wires will have some degree of capacitance between them. A capacitor is rated in farads, depending on the context the standard symbol is either ‘C’ or ‘F’. However, farad is so big such that capacitors are commonly rated in microfarads. Unlike resistors, capacitors are not usually color-coded.

    Inductors

    Inductors are commonly in the form of a coil; nevertheless, even a straight piece of a conductor has inductance. Winding a piece of a conductor into a coil concentrate magnetic field, thus, increasing inductance considerably in a given length of a conductor. Inductances are applied to the output of power amplifiers to prevent instability in the event of capacitive loads. Inductor passes DC with minimal resistance, but restrict the signal as the frequency increases, thus, an inductor can be considered the opposite of a capacitor.

    In addition, topics such as introduction to reactance, impedance, alternating current, transformers transistors, and diodes are covered in the introduction to basics electronics at a college level by students studying electornics.
