Difference 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 Hub and Bridge
Both Hubs and Bridges are network connecting devices and both of them broadcast data to every node on a network. Hubs operate at the Physical Layer and they do not perform packet filtering or addressing function; they send the data packets to all the connected devices. Bridges connect various devices in a network.A bridge operates at the data link layer to connect multiple networks. It can read the outmost section of a data packet to tell where the message is going. A bridge can be programmed to reject packets from a particular network, so it can be used to reduce ...
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 ...
Read MoreDifference between SF6 and Vacuum Circuit Breaker (VCB)
A circuit breaker is an electrical switching device that can open or close an electric circuit either normally or in case of fault. Therefore, a circuit breaker is one of the major component of an electrical power system or wiring system. A circuit breaker is usually equipped with a control mechanism which enable it to operate automatically in case of abnormal conditions in the circuit. Since the different electrical systems operate at different voltage and current levels. Therefore, according to system voltage and current, there are various types of circuit breakers available such as MCB (Miniature Circuit Breaker), ACB (Air ...
Read MoreDifference between Schottky Diode and PN Junction Diode
A diode is an electronic device that can perform switching and rectification operation in an electronic circuit. Till date, various types of diodes have been developed with the advancement in technology. In this article, we will discuss about Schottky diode and PN junction diode, and highlight the major differences between them by considering various parameters such as basic definition, circuit symbol, characteristics, applications, etc. What is a PN Junction Diode? A PN junction diode, as its name implies, a semiconductor electronic device which has two layers of oppositely charged semiconductor materials namely P-types and N-type semiconductors These two semiconductor ...
Read MoreDifference between Radar and Sonar
Both RADAR and SONAR are systems used for the detection of objects. Therefore, the primary function of a RADAR and a SONAR is the same, however both use different technologies. Read through this article to find out the major differences between RADAR and SONAR. Let's start with some basics of RADAR and SONAR. What is RADAR? RADAR stands for Radio Detection and Ranging. The RADAR is the technology used for detecting objects such as aircrafts, ships, space-crafts, guided missiles, weather formations, etc. by the use of radio waves. A RADAR measures the distance, angle and radial velocity of an object ...

MASER and LASER technologies are based on the concept of stimulated emission of radiation. In the process of stimulated emission, an electron goes to a lower energy level due to an interaction with the electromagnetic waves. In this article, we will highlight the key differences between MASER and LASER by considering various parameters. Let's start with a basic overview of MASER and LASER. What is MASER? MASER stands for Microwave Amplification by Stimulated Emission of Radiation. The MASER is a device that emits coherent electromagnetic waves through amplification by the stimulated emission of radiation. The first MASER was invented by ...
Read MoreDifference between Indicating and Recording Instruments
A device that is used for indicating and measuring various electrical quantities like current, voltage, energy, power, etc. is called a measuring instrument. Based on the functionality, the instruments can be classified in several types like indicating instruments, integrating instruments, recording instruments, etc.In this article, we will highlight all the differences between indicating instruments and recording instruments. Let's start with a basic overview of these two types of instruments. What is an Indicating Instrument? The measuring instruments which indicate the magnitude of the electrical quantity at the time when the quantity is being measured are known as indicating instruments. A ...
Read MoreDifference between HVAC and HVDC Transmission Systems
Electrical power is produced at the generating plants, from where it is transmitted over the long distances for utilization at the load points. Since, the transmission of electrical power is performed with the help of transmission conductor. Hence, due to the line parameter, some power loss occurs during the transmission. Hence, in order to reduce the power loss during the transmission, we need to take some necessary actions. One major of them is to increase the transmission voltage to higher values. The line voltage plays an important role in reducing the losses in transmission line. The increase in the line ...
