Drift Velocity, Carrier Mobility and Drift Current – Definition, Formula and Examples
The slow movement of something toward an object is termed as drift. The average velocity of electrically charged particles in a material under the influence of an electric field is called the drift velocity. In this article, we will learn in detail about drift velocity, carrier mobility, and drift current. What is Drift Velocity? When a voltage is applied across the ends of a conducting wire, an electric field is applied at every point of the copper wire. Due to this electric field, the free electrons in the conductor wire experience a force that accelerates them toward the positive end ...
Read MoreConductance and Conductivity – Definition, Unit, Formula and Examples
In this article, we shall discuss electrical conductance and conductivity, its definition, formula, unit of measurement, and the solved numerical examples. What is Electrical Conductance? The measure of how easily the electric charge (or electrons or electric current) can flow through a material is called the conductance or electrical conductance of that material. Therefore, electrical conductance defines the capability of a substance to conduct electricity. In order to understand the concept of electrical conductance, we have to recall the electrical resistance of materials. Electrical resistance is defined as the measure of difficulty that a material offers in the flow of ...
Read MoreBasic Electrical Engineering – Formulas and Equations
The branch of engineering that deals with the study of design and implementation of various electrical devices and systems used in our everyday life as well as generation, transmission and distribution of electrical power is popularly known as Electrical Engineering. Electrical engineering primarily convers the study of electric circuits, power systems, electrical machines, power electronics, control system, and many more. Electrical engineering uses formulae and mathematical equations to explain and prove the truth of concepts. These formulae and equations are very useful in understanding the behavior of electrical systems and helps to perform the different calculations in practice. This article ...
Read MoreDifference between Windmill and Wind Turbine
The energy of flowing wind is a versatile source of renewable and sustainable energy. In practice, people use the terms Windmill and Wind Turbine interchangeably, but these two terms are different from each other. Windmill and wind turbines are different from each other in structure and application. Windmill is a technology in which energy of wind is used to mill grains, moving water, driving machines, etc. On the other hand, a wind turbine converts the wind energy into electrical energy by driving a generator connected to it. In this article, we will discuss all the noticeable differences ...
Read MoreDifference between Valance Band and Conduction Band
In atomic structure, valance band and conduction band are the terms used to represent the energy levels of the subatomic particles, usually electrons. While analyzing the atomic structures, we found that the valance band and conduction band are separated by a certain amount of energy depending on the type of material. For example, in metals, these are touching each other; in semi-conductors, these are separated by a moderate amount of energy; and in case of insulators, this separation is very large. The energy gap between the valance band and the conduction band is known as forbidden energy gap. The diagram ...
Read MoreDifference between Transformer and Amplifier
In electrical and electronics engineering, transformers and amplifiers play a crucial role in several circuits. At first sight, the function of a transformer and an amplifier may seem similar, that is, increasing the level of voltage. But, a transformer can reduce the level of voltage as well, whereas an amplifier cannot. In this article, we will discuss all the key differences between a transformer and an amplifier by considering different parameters such as basic definition, circuit components, primary function, applications, etc. But before that, let's check some of the basics of transformers and amplifiers so that it becomes easier ...
Read MoreDifference between Static Relays and Electromagnetic Relays
In electrical and electronics engineering, a Relay is an electrically operated switch which is used to connect or disconnect two circuits. Since the operation of a Relay is governed by an electric control signal, hence it can be operated automatically. Basically, the relays are designed for switching of high power circuits by using low power electric signals. Depending on the technology used, the relays can be broadly classified into two types namely Electromagnetic Relays Static or Solid-State Relays In this article, we will highlight all the key differences between an electromagnetic relay and a solid state relay ...
Read MoreDifference between Resistance and Reluctance
In electrical engineering, there are two important terms resistance and reluctance related to electromagnetic circuits such as motor, generator, transformer etc. Where, the resistance is the parameter of circuit which is regarded to electric current, whereas the reluctance is the parameter regarded to the magnetic flux in the circuit. In this article, we will highlight all the significant differences between resistance and reluctance by considering different parameters such as basic definition, unit, denotation, affected quantity, etc. Let's start with some basics of Resistance and Reluctance so that it becomes easy to understand the differences between them. What is Resistance? Resistance ...
Read MoreDifference between Relay and PLC
Both relay and PLC are devices that are used in the electrical and electronic control systems for the automation of processes. A control system that is designed by using relays is known as relay logic control (RLC). Similarly, a control system that is designed by using a microcontroller and other solid state switching devices is known as programmable logic control (PLC). In this article, we will discuss all the major differences between relay and PLC by considering different parameters such as basic definition, components, function, memory, I/O, applications, etc. But before discussing the differences, let's start with ...
Read MoreDifference between Photodiode and Phototransistor
Photodiodes and Phototransistors are both semiconductor electronic devices that convert optical energy into electrical energy. Therefore, due to their similar function, one may get confused between these two devices. Both photodiode and phototransistor sense the light from a source and generate an electric signal having the strength corresponding to intensity of the light. However, these two devices are quite different from each other in many aspects. In this article, we will highlight all the significant differences between photodiodes and phototransistors. Let's start with some basics so that it becomes easy to understand the differences between them. The one most ...
