Difference between VA and Watts
Volt-Ampere and Watts are power measurement units. Volt-ampere is used to measure the total power that is being consumed by a device. Watts is used to power the device so it can perform its useful work. The product of voltage and current in an AC (alternating current) circuit is known as a unit of apparent power, or VA. It shows the overall power used by a device, which includes both the useful power used and the power lost as a result of inefficiencies like reactive power. The real power used by a gadget to carry out productive work is measured ...
Read MoreDifference between Cooler and Air Conditioner
Air coolers and air conditioners are popular electronic appliances that help cool down a room’s temperature. But these two appliances operate in completely different ways and provide different set of features. A cooler is also known as an evaporative or air cooler, which generally works by pulling in the hot air from the room and passing it over the wet pads, where it causes the water to evaporate and cools the air. The air that has been cooled is now circulated back into the room by lowering the room temperature. Coolers are more energy efficient comparing it to the air ...
Read MoreDifference between Amplifier and Receiver
An amplifier is an electronic device that is used to amplify an electrical signal without changing its other properties. It is used to amplify audio signals so that they can be played through loud speakers. It can be integrated into other appliance like a receiver or a home theatre system. A receiver is a multi-functional electronic device that combines the functions of an amplifier and a tuner. It is the home theatre system's central control unit, responsible for receiving and processing audio and video signals from various sources such as cables, satellite boxes, and Blu-ray. These signals are received by ...
Read MoreDifference Between Electromotive Force and Magnetomotive Force
The magnetomotive force is analogous to the electromotive force in an electric circuit. If an electric circuit's electrons are being propelled by an electromotive force (EMF), then the magnetic flux or field lines are being propelled by a magnetic field force (MMF). What is Electromotive Force? The passage of electrons in an electrical circuit is propelled by electromotive force (EMF). The presence of an electrical charge creates a field surrounding it, which may either attract or repulsion other charged particles. A potential difference is produced when enough of these charged particles are separated. Electromotive force is the difference in ...
Read MoreDifference between LVDS and TTL
The distinction between LVDS and TTL would be that LVDS relates to information transmission mode, whereas TTL refers to suitable transmission. In LVDS, two wires with various voltages are used, while TTL uses a ground system reference to identify the presence or absence of voltage in digital digits of 0 or 1. LVDS requires around 350mV of power. Because LVDS has excellent resistance to distortion, gadgets can use length wires. Twisted pair copper wires are employed in LVDS to produce strong electromagnet coupling. They have the capacity to stabilize voltage spikes. In contrast to TTL, the third point of reference ...
Read MoreDifference between Electric Field and Magnetic Field
There is a property of space which is caused by the motion of the electric charge, is known as electromagnetic field. There are two component of an electromagnetic field viz. −Electric fieldMagnetic fieldA stationary electric charge produces only an electric field in the surrounding space. If the electric charge is moving, then it also produces a magnetic field. The electric field and magnetic field occupy different planes relative to the cause of the electromagnetic field, i.e., moving charge.Therefore, one of the major difference between electric field and the magnetic field is that the electric field produces around a static electric ...
Read MoreWhat is Voltage Regulator 7805 – Internal Block Diagram and Applications
In this article, we will discuss the definition, internal block diagram, circuit configuration, and applications of voltage regulator 7805 IC. Let’s begin with the basic introduction of voltage regulator. A voltage regulator is an essential element of power supplies used in several electrical and electronic devices such as computers, amplifier, automobile alternator, mobile chargers, etc. A voltage regulator is basically an electronic circuit that generates a regulated voltage of fixed value from an unregulated fluctuating voltage. A voltage regulator is required in a circuit because all voltage sources cannot provide a steady voltage due to change in the load current ...
Read MoreWhat is the Nature of Electricity?
Electricity is form of energy that is obtained from other form of energy such as chemical energy, nuclear energy, heat energy, solar energy, etc. available in the nature. Electricity is the phenomenon associated with the existence and motion of the electric charge in the matter. This article is meant for explaining the nature of electricity. But before that we will understand the concept of electricity and is existence. The Concept of Electricity Electricity, also referred to as electrical energy, is a form of energy which is usually obtained from other forms of energy present in the nature. Electricity is a ...
Read MoreWhat is Space Charge – Definition, Causes, and Consequences
The collection of electrons (electric charge) at a short distance away from a metal surface forming a cloud of electric charge around the metal surface is known as space charge. These electrons are emitted from the metal surface on the application of electric field. In other words, the space charge is defined as the spatial distribution of electric charge within an insulating medium. In this article, we will discuss the definition and consequences of the space charge. What is Space Charge? As discuss above, the space charge is the accumulation or collection of electric charge in a particular region within ...
Read MoreWhat is Regulated Power Supply? – Circuit Diagram, Operation, and Applications
We have several electrical and electronic circuits that require a DC power supply to operate. But, due to some technical and economical limitations, we cannot use conventional sources of DC power such as batteries and DC generators. In this situation, we use an electronic circuit that can convert AC power into DC power, such a circuit is known as rectifier. However, the DC power output of a rectifier is a fluctuating DC voltage and current which may damage the electronic circuit. Thus, to overcome the problem of variation in voltage, some voltage regulating devices are used so that we can ...
