CT (Current Transformer) Meters are installed on any connections with a load greater than 100 Amps. Conventional meters cannot be used to measure current for these larger connections as they would simply have to be too large to be practicable. A CT meter only measures a fraction of the current passing through the connection and a multiplier is applied to this reading to reflect the actual current.
There are two types of electric meters: self-contained (direct drive) and transformer rated.
Most meters used on homes or farms are self-contained. All electric energy used passes through the meter. These meters are designed to be used on services under 200 amperes. Current transformers are contained internally.
When services are more than 200 amperes, transformer-rated meters are used. As the name implies, these types of meters use current transformers (CTs) to measure the current flow, or total power being consumed. The information is recorded by the meter.
In donut-type CTs, there are two conductors, or windings. The primary winding is the line conductor that passes through the center of the CT. The secondary winding is the multiple turns of magnet wire around the core.
The CT transforms the primary current of the line conductor to a smaller, more easily managed current that is carried to the meter which is directly proportional to the primary current. This current is inversely proportional to the number of secondary turns of wire around the iron core.
For a 200:5A CT, the turns ratio is 40:1, giving the secondary current 1/40th of the primary current. For a 400:5A CT, the turns ratio is 80:1, giving a secondary current of 1/80th of the primary current.
The Burden rating (B) is the impedance of the circuit connected to the secondary winding. This impedance is the total opposing effect to the flow of current in an AC circuit. The Burden rating is the maximum amount of impedance before exceeding the minimum accuracy limits.
The current ratio difference between the actual current (primary) and the metered current (secondary) results in what is normally referred to as the multiplier. The correction factor is the factor by which the reading of a watthour meter must be multiplied to correct for the effects of the error ratio and phase angle of the CT.

Second, Autodesk offers a free educational version that runs on up to two personal devices for 3 years. It is meant for students and educational purposes.
Go to the Autodesk Education Community.
Choose AutoCAD.
Create an Autodesk account. Alternatively, sign in to your existing Autodesk account.
Then, click DOWNLOAD NOW.
Select the desired version, your operating system, and your preferred language.
The displayed serial number and product key are sent to your email address. And click BROWSER DOWNLOAD.
Next, install the free version.
When installing the CAD software, enter the serial number, and product key to unlock it.
When you start the program the first time, activate the license.
But what if you’re in a pickle: You liked the AutoCAD free trial and find out that you need AutoCAD, but there is no way you can afford it?
In this case, Autodesk offers a slimmed down version, AutoCAD LT, that “only” costs $380 per year. Of course, you can’t expect the same feature set as in the regular AutoCAD version. The biggest difference is that the light version doesn’t support 3D modeling and visualization.

AutoCAD 360 App
Are you a smartphone jockey? Then you should take a look at AutoCAD 360. It’s a free AutoCAD version. And for a smartphone app, it’s quite capable.
The free AutoCAD 360 app is definitely more than a viewer. You can open and view DWG files, make accurate measurements and view coordinates, zoom and pan around drawings, store them in the cloud and share designs with colleagues and collaborators.
If you are willing to pay $5 a month, you get the Pro version. It offers a greater level of functionality and lets you draw, edit, move and scale objects.
But both paid and free AutoCAD 360 version lack some of the features of AutoCAD.

Available since 1982, AutoCAD is the most mature and stable CAD software on the market. As can be expected from a cutting-edge CAD program, this CAD software brings supports parametric modeling. Simply put, this enables users to make substantial changes to their designs by applying rules, or constraints, that govern their structure. Whenever the numerical value of such a constraint is changed, the entire design is modified.
Most noteworthy, a new feature in the 2018 release is the ability to import low-quality PDFs into AutoCAD and convert them into CAD lines. Moreover, the free mobile app brings CAD productivity to mobile devices which eliminates the need to print out drawings when visiting clients. As most products by Autodesk, this CAD software is connected to Print Studio, allowing you ease of access to your 3D printer.
Please note that the feature set of Windows and Mac versions differ somewhat before acquiring the AutoCAD free trial or paid version. To learn more take a look at this table on Autodesk’s website.
Use three iterations of Newton’s Method to approximate a zero of f(x) = x2 − 2. Use x = 1 as the initial guess. We need to know f (x)=2x, and we now can use the formula (we are given that x0 = 1). Use Newton’s Method to estimate the point of intersection of y = e−x2 and y = x.
If you in a Engineering College than your college may be having a licenced CATIA software for students. So, better would be to first try because I think using pirated / cracked version is not good idea.
Another , option would be to go for the TRIAL version of the software that is available on the official website of CATIA.
Or else if you do not find anywhere and could not afford the licenced version of CATIA then…..

In numerical analysis, the secant method is a root-finding algorithm that uses a succession of roots of secant lines to better approximate a root of a function f. The secant method can be thought of as a finite-difference approximation of Newton’s method.
Since water forms a concave up meniscus, the adhesion of the molecules to the glass is stronger than the cohesion among the molecules. However, in the absence of the adhesive force (when water reaches the tip of the glass), the cohesive force remains present.
