Difference between LED and LASER
Several types of devices are used to emit light. The two special devices that are used as the source of light in flashlights, traffic signals, medical instruments, etc. are LED and LASER. Both LED and LASER can emit electromagnetic radiation in the form of light. Although, these are different from each other. In this article, we will highlight all the major differences between LED and LASER. Let's start with some basic information about LED and LASER so that it becomes easy to understand the differences between them. What is LED? LED stands Light Emitting Diode. The LED is a ...
Read MoreDifference between kW and kVA
In any electric circuit (AC or DC), the electric power is one of the major electrical quantity. The electrical power is broadly classified into three types namely active power, reactive power and apparent power. These three types of electric powers are measured in different units. Where, the active power is measured in Watts (W), the reactive power is measured in Volt Ampere Reactive (VAR) and the apparent power is measured in Volt Ampere (VA). But in practice, these powers are measured in larger units, i.e., kW (kilo-Watt), kVAR (kilo Volt Ampere Reactive), and kVA (kilo Volt Ampere). Read through this ...
Read MoreDifference between Diode and Rectifier
The terms diode and rectifier are extensively used in electronics engineering. Sometimes, both these terms seam similar because they perform similar functions. However, there are many differences between a diode and a rectifier. This article is meant for explaining the differences between diode and rectifier. But before discussing the differences, it is advantageous to learn the basics of these two devices so it becomes easier to understand the differences between them. What is a Diode? A diode is a two terminal semiconductor device that allows the flow of electric current only in one direction. Therefore, the diode can ...
Read MoreDifference between CMOS and NMOS Technology
There are two most popular MOS (Metal Oxide Semiconductor) technologies namely CMOS and NMOS which are widely used in the field electronics and power electronics such as in ASICs, memories, processors, etc. Nowadays, the CMOS technology is one of the leading semiconductor technology. It is because the CMOS technology dissipates less power when compared to the bipolar and NOMOS technology. In this tutorial, we will discuss the major differences between CMOS technology and NMOS technology. But before discussing the differences, let's get a brief overview of what the CMOS and NMOS technologies are. What is CMOS Technology? CMOS stands ...
Read MoreDifference between Base Load and Peak Load Power Plant
A power plant is an interconnected system of various electrical equipment that is used to generate electricity. The major components of a power plant include an alternator (or generator), a prime mover, control system, a generating transformer, etc. The prime mover is a mechanism that drives the alternator or generator to produce electrical energy. The control system governs the parameters such as voltage, power factor, reactive power, frequency, etc. of the generating system. The generating transformer is to step up the voltage of the generated power for transmission purpose. Nowadays, several types of power plants are being used for power ...
Read MoreDifference between Avalanche Breakdown and Zener Breakdown
In a semiconductor diode, the term breakdown implies the short circuit of the diode. As we know, the diode allows the flow of electric current in only one direction (forward direction) and blocks the flow of current in the reverse direction. But, when the applied voltage in the reverse direction exceeds a limit (called breakdown voltage), the diode starts conducting in the reverse direction as well. This stage is called the breakdown in the diode. The following two types of breakdowns take place in a PN-junction semiconductor diode − Zener Breakdown Avalanche Breakdown In this article, we shall ...
Read MoreSolid State Relay vs. Electromechanical Relay
A relay is nothing but an electrically operated switch. To switch power on and off, a relay requires a low power electrical signal. Therefore, a relay is an automatically operated switch that uses low power electrical signal to control a high power electrical signal.Electromechanical Relay (EMR)As the name implies, an electromechanical relay is one that uses physically moving contact to control the flow of power in the output circuit. The movement of moving contact is generated using electromagnetic forces created by a low power input signal to the relay, which allowing the completion of the circuit that contains high power ...
Read MoreDifference between Vacuum Tube and Transistor
Vacuum tube and Transistor are types electronic switching devices used a variety of electronic devices and circuits such as computers, communication systems, power supplies, TV, radios, amplifiers, etc. However, both are significantly different from each other based on their technology and operation. In this article, we will highlight all the points that differentiate a vacuum tube from a transistor. Let's start with some basics of vacuum tubes and transistors. What is a Vacuum Tube? A vacuum tube is an electronic device used to control the current flowing in a circuit using a vacuum in a sealed glass tube. Basically, ...
Read MoreDifference between Wattmeter and Energy Meter
In every electrical system, we need to measure various electrical quantities such as current, voltage, power, energy, etc. For this purpose various types of measuring instruments have been developed to measure the respective quantity. Go through this article to find out more about wattmeter and energy meter. We also learn about the significant differences between a wattmeter and energy meter. One major difference between wattmeter and energy meter is that the wattmeter measures electrical power in the circuit, whereas the energy meter measures total amount of energy consumed by the load.What is a Wattmeter? A wattmeter is an ...
Read MoreDifference between Galvanic Cell and Electrolytic Cell
A cell is a device which can convert chemical energy into electrical energy. A cell consists of two electrodes and chemical substances inside it. When the cell is connected in a circuit, the chemical reactions take place inside the cell and as a result of these chemical reactions, an electric current flows in the circuit. In this article, we will discuss about galvanic cells and electrolytic cells and how these two types of cells are different from each other.What is a Galvanic Cell?A galvanic cell is an electrochemical cell in which an electric is produced from spontaneous oxidation-reduction reactions.The galvanic ...
