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 MoreWhat is meant by Market Targeting?
Market Targeting − DefinitionA corporation cannot focus on all market segments at the same time. Only a few segments can be satisfied by the company.The act of picking the target audience from the total market is known as market targeting. The target market is made up of a group or groups of purchasers who the company intends to serve or for whom the product is developed, with a price established, promotion efforts performed, and a distribution system in place.For example, consider a sandwich shop in a suburban town that is near to a petrol station. Because of its proximity to ...
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 Power Transformer and Distribution Transformer
Power transformers and Distribution transformers are extensively used in power systems for stepping up and down the voltage level for various applications such as transmission and distribution. Read through this article to find out the major differences between power transformers and distribution transformers and how they function.What is a Transformer?A Transformer is a static electrical machine which changes the level of voltage and current in a circuit without changing the frequency of the supply. Transformers works on the principle of electromagnetic induction.Based on the design, operation, purpose of use, transformers are classified into different types such as auto-transformer, current transformer, ...
Read MoreDifference between LED and Halogen
LED lamps consume less energy as compared to Halogen lamps. LED lamps are cost efficient too. Read through this article to find out the major differnces between LEDs and Halogen lamps and how they function.What is LED Lamp?An electric lamp which produces light by using light emitting diodes or LEDs is known as an LED lamp or LED light bulb. An LED lamp works on the principle of electroluminescence, i.e. it emits the light due to the interaction of an electric field with a suitable solid.Basically, an LED is a specially doped PN junction diode which is made of special ...
Read MoreDifference between Series and Parallel Circuit
Series and Parallel electric circuits are heavily used in various applications such as resistive series circuits, voltage divider circuits, home appliances, etc. It is important to have a good knowledge of how these circuits work. Go through this article to get an overview of how Series and Parallel circuits operate and how they differ from each other.What is an Electric Circuit?An electrical network which has closed path for electric current to flow is known as electric circuit or circuit. An electric circuit consists various circuit elements such as energy sources, resistors, inductors, capacitors, etc. An electric circuit must have at ...
