Is a ad in a magazine primary or secondary information?

well, an ad isn't typically a source of information. if you mean an article in a magazine, then it is secondary info. primary is things that are evidence, and directly from the scene, like (but not limited to) artifacts or diaries. a secondary source is information pulled from primary sources by someone else, like articles, books, videos, etc. (but i think videos taken directly of an incedent are still considered primary sources).


What is the type of root system present in jowar?

The root system of the Jowar plant can be divided into a primary and secondary root system. The primary system has a primary root that develops from the germinating seedling and provides the seedling with water and nutrients required for growth. The primary root is short-lived, and the function of the primary root is taken over by a secondary root system. The secondary system develops from the root crowns that are located just under or above the soil. The root system of an adult Jowar plant is made of secondary adventitious roots. Lateral roots develop from the secondary adventitious roots and penetrate the soil in all directions.


What is the source of energy that flows through most of the food chains on earth?

The energy is taken from nutrients that are found in the ground which the plants absorb. The plants are then eaten by primary consumers, or herbivores;after this, the primary consumers re eaten by secondary consumers or carnivores. Omnivores share both of these characteristics though, and thus are a primary and secondary consumer.


Why do you use current transformer in a relay circuit?

CTs are used where the primary current and voltage are high and hence can not be directly taken into control circuit. By using a CT the corresponding current of primary current is made available on the secondary side, which are low and be taken in to control circuits conveniently.

What is primary side in transformer?

Transformers have a primary side and a secondary side. The primary side is (sometimes) the higher voltage side and, consequently, the secondary side is (sometimes) the lower voltage side.A voltage transformer may be used to obtain a lower, or a higher, voltage from an existing voltage.The primary winding is the winding to which the voltage to be transformed is applied.The desired voltage (after transformation) is taken from the secondary winding.AnswerA transformer's primary winding, by definition, is the winding connected to the supply (i.e. its input side), and its secondary winding is the winding connected to the load (i.e. its output side). It's as simple as that! It has nothingwhatsoever to do with the voltage levels! It applies to step-up, step-down, or to isolation (1:1) transformers.

Have a step up tranformer. 110 volts to 220 volts. Power 550VA. Can I connect the secondary to 220 volts and get 110 volts form the Primary and use this 110 volts to run an equipment that draws 2 amps?

firstly please know what is ment by secondary and primary? primary-it means power is given to that port secondary-it means power is taken from that port you can use the transformer in any mode that meas you can give power to primary for taking power from secondry and vice versa. you can use the power delivered by the transformer from the secondry for any purpouse


What is vector group dyn11 in transformer?

Vector group means it defines the primary & secondary side connection type of the transformer. It says D for the delta connections (windings connected between two phases) & Y for the star connections (windings connected from each phase to ground). The 11 stands for the phase displacement of the secondary referenced to the primary. Imagine a clock with only an hour hand; at 11 o'clock, the hand is at 30 degrees to the reference (12 c'clock), so the secondary is at 30 degrees to the primary.D or d means delta connectionY or y means star/wye connectionz means zed/zigzag/interconnected star connectionN or n means the Neutral point is accessible in the star connection. This is also sometimes taken to mean that the neutral point is earthed.A number means a phase shift in the secondary with respect to the primary, where the phase is measured in "hours"A capital letter indicates primary winding and lower case secondary. Capital z does not occur as zed transformers are used only for creating an earth on an unearthed system and thus are always on the earthed secondary.Primary is taken to be the higher voltage side, regardless of the direction of power flow.So, Dyn11 means delta primary, star secondary leading the primary by 30 degrees, possibly with an earthed neutral


Write detail note on secondary storage devices?

Secondary storage (also known as external memory or auxiliary storage), differs from primary storage in that it is not directly accessible by the CPU. The computer usually uses its input/output channels to access secondary storage and transfers the desired data using intermediate area in primary storage. Secondary storage does not lose the data when the device is powered down---it is non-volatile. Per unit, it is typically also two orders of magnitude less expensive than primary storage. Consequently, modern computer systems typically have two orders of magnitude more secondary storage than primary storage and data are kept for a longer time there. In modern computers, hard disk drives are usually used as secondary storage. The time taken to access a given byte of information stored on a hard disk is typically a few thousandths of a second, or milliseconds. By contrast, the time taken to access a given byte of information stored in random access memory is measured in billionths of a second, or nanoseconds. This illustrates the significant access-time difference which distinguishes solid-state memory from rotating magnetic storage devices: hard disks are typically about a million times slower than memory. Rotating optical storage devices, such as CD and DVD drives, have even longer access times. With disk drives, once the disk read/write head reaches the proper placement and the data of interest rotates under it, subsequent data on the track are very fast to access. As a result, in order to hide the initial seek time and rotational latency, data are transferred to and from disks in large contiguous blocks.When data reside on disk, block access to hide latency offers a ray of hope in designing efficient external memory algorithms. Sequential or block access on disks is orders of magnitude faster than random access, and many sophisticated paradigms have been developed to design efficient algorithms based upon sequential and block access. Another way to reduce the I/O bottleneck is to use multiple disks in parallel in order to increase the bandwidth between primary and secondary memory.[3]Some other examples of secondary storage technologies are: flash memory (e.g. USB flash drives or keys), floppy disks, magnetic tape, paper tape, punched cards, standalone RAM disks, and Iomega Zip drives.The secondary storage is often formatted according to a file system format, which provides the abstraction necessary to organize data into files and directories, providing also additional information (called metadata) describing the owner of a certain file, the access time, the access permissions, and other information.Most computer operating systems use the concept of virtual memory, allowing utilization of more primary storage capacity than is physically available in the system. As the primary memory fills up, the system moves the least-used chunks (pages) to secondary storage devices (to a swap file or page file), retrieving them later when they are needed. As more of these retrievals from slower secondary storage are necessary, the more the overall system performance is degraded.


What happens to the current as the voltage is increased by the step up transformer?

Compare a transformer to a balancing act. Both side need to remain equal.The primary side of the transformer is the supply side and the load is connected to the secondary side of the transformer.The load governs the current of the secondary side of the transformer and the voltage of the secondary side must match the voltage that the load required to operate.The ratio of the transformer will determine what the voltage of the secondary side is as compared to the voltage that has to be applied to the primary.The current of a step up transformer will be higher on the primary side that that of the secondary.Apply voltage and current to this concept and you will see that the transformer will remain balanced.The size of the transformer is always calculated from the secondary side of the transformer and the value is written in VA or KVA where V = voltage and A = amperage. Power factor is also taken into consideration when calculating the size of the transformer to be used.


What do we call the voltage that is provided by a transformer?

This is the transformed voltage, but it might also be identified as the secondary voltage as it is taken from the secondary winding.


Does beer cause memory loss?

Alcohol in any form, when taken excessively, is able to cause short-term amnesia (blackouts), and can also affect our ability to retrieve information from long-term memory. Contrary to popular belief, we do not pass out in a blackout. It refers, instead, to the loss of memories about things we do when we are conscious. It is also one of the first signs of advanced alcoholism.


How do you set up a transformer efficiency test?

You'll need a clean, stable primary side voltage source. You'll measure and monitor it throughout the test. You will need to measure primary current, too. You'll need a stable secondary resistance of known value, and you'll have to monitor voltage across it throughout the test. If you want to measure current, you can use an "unknown" resistance - as long as it is stable. You have a choice, and you can make your calculations based on either one. Your equipment will have to be "accurate" at least to the degree of accuracy you wish in your results. Hook up your resistance to the secondary, hook your equipment up to the various places you'll need it to make your measurements, plug in the primary and flip the switch. Observe and record. Your data will allow you to make calculations. Primary voltage times primary current equals primary power (power into the primary). Secondary voltage times secondary current will equal secondary power (power out of the secondary). There wil be a bit more power "put into" the primary than is "taken out of" the secondary because of losses within the transformer. (These will be resistive losses in the wire as well as inductive losses in the core - eddy currents.) And that is what efficiency speaks to. Transformer efficiency can be calculated using the following formula: Efficiencytransformer in % = 100 x (Powersecondary / Powerprimary) If you opt to use secondary voltage and the resistance of the resistive load to make your calculations for the secondary side power, it will be found by using this formula: Powersecondary = (Voltagesecondary)2 / Resistanceload Either path should lead to the same destination. And just so you know, if you use secondary current and the resistance of the load to make the calculation, that is done using this formula: Powersecondary = (Currentsecondary)2 x Resistanceload All roads lead to Rome.
