Main Content




Basic Concepts of Electricity and Electronics




The first part of Electrical and Electronic Principles and Technology PDF 28 covers the basic concepts of electricity and electronics. These include voltage, current, resistance, and power; Ohm's law and Kirchhoff's laws; and series and parallel circuits. These concepts are essential for understanding the behavior and characteristics of electrical and electronic components and devices.


Voltage, Current, Resistance, and Power




Voltage is the measure of the potential difference between two points in an electric circuit. It is also called electromotive force (emf) or electric potential. Voltage is measured in volts (V) and is represented by the symbol V or E. Current is the measure of the rate of flow of electric charge in an electric circuit. It is also called electric current or simply current. Current is measured in amperes (A) and is represented by the symbol I. Resistance is the measure of the opposition to the flow of electric current in an electric circuit. It is also called electrical resistance or simply resistance. Resistance is measured in ohms (Ω) and is represented by the symbol R. Power is the measure of the rate of work done by an electric circuit. It is also called electric power or simply power. Power is measured in watts (W) and is represented by the symbol P.


Ohm's Law and Kirchhoff's Laws




Ohm's law is a mathematical equation that relates voltage, current, and resistance in an electric circuit. It states that the voltage across a resistor is equal to the product of the current through it and its resistance. The equation can be written as V = IR, where V is voltage, I is current, and R is resistance. Kirchhoff's laws are two rules that apply to any electric circuit. They are based on the conservation of charge and energy in an electric circuit. The first rule, known as Kirchhoff's current law (KCL), states that the sum of the currents entering a node (a point where two or more wires meet) is equal to the sum of the currents leaving that node. The second rule, known as Kirchhoff's voltage law (KVL), states that the sum of the voltages around a closed loop (a path that starts and ends at the same point) is equal to zero.


Series and Parallel Circuits




A series circuit is a type of electric circuit where there is only one path for current to flow. In a series circuit, all the components are connected end to end, forming a single loop. The total resistance of a series circuit is equal to the sum of the individual resistances of each component. The total voltage of a series circuit is equal to the sum of the individual voltages across each component. A parallel circuit is a type of electric circuit where there are two or more paths for current to flow. In a parallel circuit, all the components are connected across each other, forming multiple loops. The total resistance of a parallel circuit is equal to the reciprocal of the sum of the reciprocals of the individual resistances of each component. The total voltage of a parallel circuit is equal to the voltage across any component.


Electrical Components and Devices




The second part of Electrical and Electronic Principles and Technology PDF 28 covers some common electrical components and devices that are used in various electrical and electronic circuits and systems. These include resistors, capacitors, inductors, and transformers; diodes, transistors, LEDs, and switches; and relays, motors, generators, and batteries. These components and devices have different functions and properties that affect their performance and behavior in an electric circuit.


Resistors, Capacitors, Inductors, and Transformers




Resistors, Capacitors, Inductors, and Transformers




A resistor is a component that limits or controls the flow of current in an electric circuit. It has a fixed or variable resistance value that determines how much current can pass through it for a given voltage. A capacitor is a component that stores electric charge in an electric circuit. It has two conductive plates separated by an insulator called a dielectric. A capacitor has a capacitance value that determines how much charge it can store for a given voltage. An inductor is a component that stores magnetic energy in an electric circuit. It has a coil of wire wrapped around a core of iron or air. An inductor has an inductance value that determines how much magnetic energy it can store for a given current. A transformer is a device that transfers electric energy from one circuit to another through electromagnetic induction. It has two coils of wire called the primary and secondary windings that are linked by a magnetic core. A transformer can change the voltage and current levels of an electric circuit by varying the number of turns in the windings.


Diodes, Transistors, LEDs, and Switches




A diode is a component that allows current to flow in one direction only in an electric circuit. It has two terminals called the anode and cathode that are connected to a semiconductor material such as silicon or germanium.

An analog signal is a type of signal that varies continuously in time and amplitude in an electronic system. It can represent any physical quantity such as sound, light, temperature, or pressure. An analog signal can be measured by using devices such as voltmeters, oscilloscopes, or microphones. A digital signal is a type of signal that varies discretely in time and amplitude in an electronic system. It can represent only two values such as 0 or 1, or on or off. A digital signal can be measured by using devices such as logic analyzers, multimeters, or speakers.


Logic Gates, Flip-Flops, and Counters




A logic gate is a component that performs a basic logical operation on one or more digital signals in an electronic system. It has one or more inputs and one output that can be either 0 or 1, depending on the type of operation. There are seven basic types of logic gates: AND, OR, NOT, NAND, NOR, XOR, and XNOR. A flip-flop is a component that stores one bit of digital information in an electronic system. It has two stable states called the set and reset states that can be either 0 or 1, depending on the input signals. There are four basic types of flip-flops: SR, D, JK, and T. A counter is a component that counts the number of pulses in a digital signal in an electronic system. It has a series of flip-flops that store the binary representation of the count value. There are two basic types of counters: synchronous and asynchronous.
