Difference between Generator and Inverter
The interruption in the supply of electricity has increased drastically over the years due to increased demand and it influenced the electricity industry. To overcome the problem of irregularities in the electricity supply, two of the most common technologies viz. generator and inverter of electric power supply are used. The generator and inverter both are the power backup devices used in case of electricity failure to produce electric supply without any disruption.In this article, we will discuss the differences between the generator and inverter on the basis of various parameters such as voltage, starting time, installation, maintenance, size and cost, ...
Read MoreDifference between EMF and Voltage
EMF and Voltage are the two fundamental aspects of electrical and electronics engineering. They may appear as same, but they are different electrical quantities. In order to understand the difference between EMF and voltage, we first need to understand their meaning.What is EMF?EMF stands for Electromotive Force. The measure of energy the power source (ex. Battery) gives to each Coulomb of charge is known as EMF of the power source or battery. The EMF is denoted by letter ‘E’. The SI unit of EMF is the same as the voltage, which is Volts.The EMF is the factor which creates and ...
Read MoreDifference between Conduction and Convection
Both conduction and convection are modes of heat transfer from one system to another. When there is a difference in the temperature of two systems, then the transfer of heat takes place from the system of higher temperature to the system of lower temperature.In practice, this transfer of heat takes place in three different modes viz. conduction, convection and radiation. But, in this article, we will only discuss about conduction and convection and how they are different from each other.What is Conduction of Heat?When the transfer of heat takes place from one part of the substance to another part without ...
Read MoreDifference between Battery and Capacitor
Both Battery and Capacitor seem to be similar in the first glance because they store and release the electric energy, but there are many differences between them which we are going to highlight in this article.One of the most significant differences between a battery and a capacitor is that a battery stores electrical energy in the form of chemical energy and again converts it into electrical energy when required, while a capacitor stores electrical energy in the form of electrostatic field.What is a Battery?A battery is a device which is used as the source of energy in electrical and electronic ...
Read MoreDifference between NPN and PNP Transistor
A transistor (or bipolar junction transistor) is a three-terminal, three-layer and two-junction semiconductor device, used as the digital switch and amplifier in the electronic circuits.A transistor consists of three layers of P-type and N-type semiconductor materials and the name of these layers are emitter, base and collector. The three terminals are taken out from these three layers.Based on the arrangement of the semiconductor layers, the transistors are of two types as −NPN TransistorPNP TransistorRead through this article to find out more about NPN transistor (BJT) and PNP transistor and the key differences between them.What is NPN Transistor?An NPN transistor is ...
Read MoreDifference between Alternating Current and Direct Current
The directed flow of electrons or charge in an electric circuit is known as electric current. Based on the nature of flow of electrons (or electric current), the electric current is classified into two types: AC (Alternating Current) and DC (Direct Current). Go through this article to find out more about AC and DC and how they are different from each other.What is Alternating Current?AC stands for Alternating Current. The type of electric current whose magnitude changes continuously and direction changes periodically is known as alternating current or AC. In practice, the alternating current is produced by alternating voltage source ...
Read MoreDifference Between Multimeter and Voltage Tester
Multimeters and voltage testers are both testing and measuring devices that are used to measure a wide range of electrical quantities. Go through this article to get a basic understanding of how multimeters and voltage testers work and how exactly they are different from each other.What is a Multimeter?A multimeter is a standard measuring instrument that is used for measuring multiple electrical quantities in an electric circuit. With a typical multimeter, one can measure AC voltage and current, DC voltage and current, resistance, continuity, and other values.Basically, a multimeter is a combination of a DC voltmeter, AC voltmeter, DC ammeter, ...
Read MoreDifference between Diode and Transistor
Both diodes and transistors are types of semiconductor devices that find a wide range of applications in different electronic circuits such as clippers, clampers, oscillators, rectifiers and amplifiers, etc. Go through this article to get an overview of how diodes and transistors function and how they are different from each other.What is a Diode?A diode is a semiconductor switching device which is constructed by combining two layers of N-type and P-type semiconductor materials. For this reason, a diode is also called as PN junction diode. The circuit symbol of the diode is shown in Figure-1.A diode has only one PN-junction ...
Read MoreDifference between Multimeter and Voltmeter
Multimeter and Voltmeter are handheld measuring devices. Voltmeters are used when one needs to measure only voltage. Multimeters, in contrast, can be used to measure multiple electrical quantities such as current, voltage, resistance, etc.Go through this article to find out the features of multimeters and voltmeters and how they differ from each other.What is a Multimeter?Multimeter, as the name implies, is a combination of different measuring instruments in a single unit. It can measure several electrical quantities such as current, voltage, resistance, etc. An extended version of multimeter can also measure other electrical properties like transistors gain, diode forward voltage, ...
Read MoreDifference between Electrical Engineering and Electronics Engineering
Electrical engineering deals with the study of how to generate, transmit and utilize the electrical energy. Electronics engineering, on the other hand, deals with the study of how to control and switch the flow of electrical energy in a circuit. Go through this article to find out the other major differences between electrical and electronics engineering.What is Electrical Engineering?Electrical engineering is the branch of engineering which deals with the generation, transmission, distribution and utilization of electrical energy.Electrical engineering is also concerned with study and design of electrical machines. The field of electrical engineering provides solutions for problems in various fields ...
