What is secondary data?
Secondary data is collecting and possibly processing data by people other than the researcher in question. Common sources of secondary data for social science include censuses, large surveys, and organizational records (Mintel). In sociology primary data is data you have collected yourself and secondary data is data you have gathered from primary sources to create new research. In terms of historical research, these two terms have different meanings. A primary source is a book or set of archival records. A secondary source is a summary of a book or set of records. Advantages to the secondary data collection method are - 1) it saves time that would otherwise be spent collecting data, 2) provides a larger database (usually) than what would be possible to collect on ones own However there are disadvantages to the fact that the researcher cannot personally check the data so its reliability may be questioned.
How do you calculate in CT ratio?
The CT (Current Transformer) ratio is calculated by dividing the primary current (the current flowing through the primary circuit) by the secondary current (the current flowing through the secondary circuit). The formula is CT Ratio = Primary Current (Ip) / Secondary Current (Is). For example, if a CT is designed to handle 100 A on the primary side and outputs 5 A on the secondary side, the CT ratio would be 100 A / 5 A = 20:1. This means that for every 20 A flowing in the primary circuit, 1 A will flow in the secondary circuit.
Explain the difference beteween primary sources of information and secondary sources of information.Identify which would be more helpful to you are looking for information concerning the animal that a?
a primary source would be first hand from an educated certified doctor or something like that. a secondary source would be information from someone...like me!
What is primary source of information?
There are two kinds of sources...primary and secondary. A primary source is information you see with your own eyes. An example would be a book written in first person, or a newspaper article. A secondary source is information that has been passed on. An example of this would be a gossip magazene or fiction book. Hope this helps :)
What is a Venn diagram to compare primary and secondary succession?
A Venn diagram comparing primary and secondary succession visually represents their similarities and differences. Primary succession occurs in lifeless areas where soil is initially absent, such as after a volcanic eruption, while secondary succession takes place in environments that have been disturbed but still retain soil, like after a forest fire. Both processes involve stages of colonization by organisms, leading to a climax community, but primary succession takes longer due to the lack of soil. In the Venn diagram, the overlapping section would highlight commonalities, such as ecosystem development and species interactions.

Explain the difference between primary data and secondary data give an example of each?
Primary data is data collected firsthand, through surveys, interviews, experiments, etc. by the researcher, while secondary data is existing data that has already been collected by someone else. An example of primary data would be survey responses collected by a marketing team for a new product. An example of secondary data would be industry reports or census data obtained from a government website.
Advantage of primary research?
Primary research is how the human race discovers new things. Secondary research only allows you to learn about what others have already discovered (which is also important, of course, but not as important, since without primary research there would be no secondary research either).

Formula for relation between primary winding and secondary winding?
The turns ratio of Primary / Secondary tells you have the voltage and current will be changed. The secondary current will be (primary turns/secondary turns) times the primary current, and the secondary voltage will be (secondary turns / primary turns) times the primary voltage.CommentThe above answer is a little misleading, because the secondary current is determined by the load, and not by the transformer's ratio. It would, therefore, be more accurate to say that the primary current would be equal to the secondary current times the (primary turns/secondary turns) -i.e. not the other way around!
What is the current in the secondary coil if current in primary is 5.0A?
It depends on the turns ratio between the primary and the secondary. If the ratio were 10:1, a step-down transformer, for instance, the current in the secondary would be about 50A. If it were 1:10, a step-up transformer, however, the current in the secondary would be about 0.5A.AnswerThe primary current doesn't determine the secondary current. The secondary current is entirely-dependent on the secondary voltage and the impedance of the load. It is this secondary current that the determines the primary current. So you should be asking, "What value of secondary current would result in a primary current of 5.0 A?"
What is secondary relationship?
A secondary Relationship is anything outside of the primary relationship. If you have a wife(Primary or should be) and a girlfriend(Secondary). This is what a secondary relationship would look like and this is an inappropriate relationship.
What would be followed by secondary succession?
Primary succession. Follow the answer to "What is secondary succession?".
