What are the types of electrical loads? Three basic types of loads exist in circuits: capacitive loads, inductive loads and resistive loads. These differ in how they consume power in an alternating current (AC) setup. Capacitive, inductive and resistive load types correspond loosely to lighting, mechanical and heating loads. What is an inductive load? Reactive/Inductive […]

What are the 8 periods of development? Developmentalists often break the lifespan into eight stages: Prenatal Development. Infancy and Toddlerhood. Early Childhood. Middle Childhood. Adolescence. Early Adulthood. Middle Adulthood. Late Adulthood. What are the 7 stages of development? There are seven stages a human moves through during his or her life span. These stages include […]

What is the operating principle of LED? Working Principle: A light-emitting diode is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of […]

Which individual is a producer a host who seats? Answer: To be considered as a producer, we need to create some sorts of goods or services and exchange it with the customers in order to obtain some sort of financial gain. I believe that a host who seats customers in a busy restaurant would be […]

How many methods of coal analysis are there? two methods How do you know the grade of coal? The most common classification is based on rank, referring to the degree of coalification that has occurred. The rank of a coal is determined primarily by the depth of burial and temperature to which the coal was […]

Why does my straw look bent in water? Refraction is the bending of light as it passes from one medium into another (ie. As you look at the straw in the glass of water, the light coming from the straw to your eye bends as it passes through three different mediums (water, glass, and air). […]

Is neuropsychology a stem? NSF considers it (and other social science fields) part of STEM, as do many other organizations and universities. US Immigration considers psychology a STEM field as well. Is psychology considered a STEM field? Psychology is a core STEM discipline because of its direct scientific and technological innovations, as well as its […]

What are 2 ways energy can be transferred? The two ways that energy can be transferred are by doing work and by heat transfer. How is thermal energy transferred within a system? Generally, when thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three […]

How does the TCP sender understand whether there is congestion in the network? TCP detects congestion when it fails to receive an acknowledgement for a packet within the estimated timeout. Both these algorithms depend on counting duplicate acknowledgements sent by the data receiver in response to each additional segment received following some missing data. Does […]

What is clarification in water treatment? Clarification is an essential step in a water or wastewater treatment process to remove suspended solids through gravity settling, providing a clarified liquid effluent. A secondary function of a clarifier is the removal of floating matter (scum), which has accumulated on the water surface. What is the first step […]
