The AIC rating specifies the maximum available fault current that an overcurrent protection device will safely clear when a fault is applied to the overcurrent protection device's load side. The AIC rating is only applicable to overcurrent protection devices. It is irrelevant to standard relay, and standard relays do not have an AIC rating.

Power over Ethernet

What is Power over ethernet?

POE stand is a wired ethernet local area network implementation technology that allows the electrical current required to operate each device to be carried by ethernet data cables rather than standard electrical power cords and wiring.

PoE which is used in both smart home applications and business premises uses less expensive Ethernet cabling that can transport both power and data instead of electrical wiring, which only supplies power and requires separate wiring for data. PoE transport both power and data over cable, less wiring is required and existing electrical wiring can be reused.

PoE was created in 2003 to support devices such as wireless access points. Individual vendors previously used various forms of proprietary PoE to provide PoE capabilities. Some of these proprietary PoE devices are still in use. PoE installer must locate these older, proprietary devices because they can be troublesome or incompatible with later released standard PoE devices. Today's standard PoE devices make AP installations simpler and more adaptable in ceilings that can wire for electrical power.  

Why should you use PoE?

Power over Ethernet provide numerous benefits to an installation:

  • Saving in time and money -  By reducing the time and cost of installing electrical power cabling. Network cables do not need to be installed by a qualified electrician and can be placed anywhere.
  • Flexibility -  Because they are not tethered to an electrical outlet, devices such as IP cameras and wireless access points can be placed wherever they are most needed and easily repositioned if necessary.
  • It is intelligent and designed to protect network equipment from overloading, uploading, or incorrect installation.
  • Reliability -  Rather than a collection of distributed wall adapters, PoE power comes from a centralized and universally compatible source. It can be powered by an Uninterruptible power supply  or remotely controlled to easily disable or reset devices.
  • Scalability - It is having enough power on the network to make installation and distribution of network connection simple and efficient.

Answer:

  • Power Over Ethernet

What does POE mean?


POE is a method of delivering direct current power to devices via copper ethernet cabling, eliminating the need for separate power supplies and outlets. While PoE does not add data capabilities to ethernet, it does provide more flexibility in how and where the ethernet end device can be placed.

PQEP is a IC package with leads extending from all four sides of the package body, PQFP are mostly square, but there are some rectangular variants. The PQFP is one of the several quad flat pack package type.

PPGA full form

 What is the full form of PPGA?

Answer:

  • Plastic Pin Grid Array

What does PPGA mean?

PPGA is a square-shaped plastic package with pins or leads arranged in a square array at the package bottom. The PPGA is just one of the several PGA package types. A PGA package can provide much higher lead counts than other packages due to the array arrangement of the leads. This is why the PGA is a popular choice for devices with a high number of I/Os such as a microprocessor.

SONAR full form

 What is the full form of SONAR?

Answer:

  • Sound Navigation and Ranging

What does SONAR mean?

SONAR is a sound propagation-based technique. It uses sound propagation to navigate, communicate or detect objects beneath or on the surface of the water. Because sound waves travel farther in water than radar and light waves, this technology is useful for exploring and mapping oceans. SONAR assists NOAA scientists in the development of nautical charts for the detection of underwater hazards to navigation, and mapping of objects on seafood such as shipwrecks.

RADAR vs SONAR | Difference | Comparison | Explained Simply

Both RADAR and SONAR are detection systems that can be used to identify and locate objects that are not visible or at a great distance. They are similar in that they both detect the reflected signal of a previously transmitted signal.

RADAR vs SONAR:

  • RADAR stands for radio detection and ranging device, while SONAR stands for sound ranging and navigation device.
  • A radar helps to find or acknowledge us of the unwanted object or bodies that may come in our path and may prove to be dangerous for use, while the sonar is a navigation and ranging device that uses sound waves or signals to recognize unwanted bodies or objects.
  • RADAR is for detection purposes, radar uses radio waves, while SONAR is used for navigating purposes, SONAR uses sound waves.
  • The frequency range of RADAR is 50-330MHZ, while the SONAR frequency range is 100KHZ to 1MHZ.
  • RADAR is mostly used in space, spacecraft, and aeroplanes, for example, whereas SONAR is mostly used for water communication and ranging examples.
  • The maximum range of RADAR is 100-350 KM, while the SONAR max range is 482 km.
  • The speed of RADR is more than SONAR, While SONAR has less speed than RADAR.
  • The propagation speed of RADAR is 1500 variable, while the SONAR propagation speed is 3*108 m/sec, constant.

 What is the full form of RADAR?

Answer:

  • Radio Detection & Ranging

What does RADAR mean?


RADAR is an electronic object detection device that uses ultra high frequency or microwave part of the radio frequency spectrum to determine an object position or range. It can also be used to determine a moving objects speed and direction. During the second world war, many counties worked in secret to develop it. The US navy coined the term RADAR in 1940.

Adhesion Vs Cohesion

Cohesion is the ability of similar molecules to stick together due to mutual attraction. The ability of different molecules or surfaces to cling to each other is referred to as adhesion. So here this article gives the difference between adhesion vs cohesion to better understand this topic.

Adhesion Vs Cohesion:

  • Adhesion happens between two dissimilar molecules or substances, while the cohesion is two similar substances face the force of attraction this force is known as a cohesion force.
  • Adhesion is generally the force of attraction present between the water molecules and the walls of xylem vessels, while the cohesion force is rampant among water molecules.
  • Cohesion is caused by hydrogen bonding and van der Waals forces, whereas adhesion is caused by electrostatic or mechanical forces that exist between two types of different substances.
  • Capillary action and meniscus are the effects of adhesion, while the surface tension, meniscus, and capillary action are the effects of cohesion.
  • A strong adhesion force spreads the liquid all over the surface, whereas a strong cohesion force forms water droplets on any surface.
