Kirchhoffs Current Law Essay Example

Kirchhoffs Current Law Paper In 1845, a German physicist, Gustav Kirchoff developed a pair or set of rules or laws which deal with the conservation of current and energy within electrical circuits. These two rules are commonly known as: Kirchoffs Circuit Laws with one of Kirchof’s laws dealing with the current flowing around a closed circuit, Kirchoffs Current Law, (KCL) while the other law deals with the voltage sources present in a closed circuit, Kirchoffs Voltage Law, (KVL). Kirchoff’s first law that is KCL states that the total current or charge entering a junction or node is exactly equal to the charge leaving the node as it has no other place to go except to leave, as no charge is lost within the node. In other words the algebraic sum of all the currents entering and leaving a node must be equal to zero. This idea by Kirchoff is commonly known as the Conservation of Charge. The term node in an electrical circuit generally refers to a connection or junction of two or more current carrying paths or elements such as cables and components. Also for current to flow either in or out of a node a closed circuit path must exist. We can use Kirchoffs current law when analyzing parallel circuits.  Kirchoff’s second law that is KVL states that in any closed loop network, the total voltage around the loop is equal to the sum of all the voltage drops within the same loop which is also equal to zero. In other words the algebraic sum of all voltages within the loop must be equal to zero. This idea by Kirchoff is known as the Conservation of Energy. Comment: All the value of result in the experiment was awfully close to the theoretical value and therefore, in this part of the experiment it shows that the KVL and KCL are true and can be applied.

From experiment Part A,B,and C we had Vsupply = 10.02 V .An error was occurred because Vsupplys should 10.0 v.This is because the instrumental error was occurred.So,to overcome this problem,the students should be able use the instrument correctly and the technician should keep instrument optimized.When we doing practical for part A ,we\does not have many problem ,this because the objective for this experiment we have absolutely achieve . But absolute error was occurred.For the example,experiment A set 1 an absolute error was occurred,Absolute error is different between the expected value and the measured value. e= Yn- Xn where e=absolute error  Yn= expected value  Xn=measured value  e=10.02-10.0  =0.02v  Error in percentage:  % error= e/Yn (100) = 0.02/10.02 (100) = 1.99%  2.Beside that, when we run our experiment, we always have different thinking to get better result.Thus, the gross error was occurred. Example, we have incorrect reading when we measured the multimeter. Also, parallax error should be taken into consideration. Parallax error is the error that human make when taking a reading from any device where our eyes are not perpendicular to the scale reading. To overcome this problem, we carefully read the scale reading to minimize any fault.  3.Next, the problem that our group have come to face is incorrect reading of the multimeter, voltmeter and ammeter. We suspected that the fault was caused by the instrument itself. To overcome this problem, we take at least three separate reading to obtain better reading.  Conclusion  From the experiment that we had conducted, we had practically use Kirchoff Law to determine the voltage drop, voltage supplied, current for each resistor in series and parallel circuit.

Some Notes to Consider When Controlling the Topic of Your Research Paper

Some Notes to Consider When Controlling the Topic of Your Research PaperIt can be very difficult to categorize the given topics for a literary analysis essay as strong or weak. It will take you time to formulate your basic conclusion. Also, remember that it is your opinion and not the textbook's. But still, your opinion will certainly matter a lot.When considering the topic as strong, you can also consider the question: 'What is the main theme of this essay?' This will help you to categorize your argument in a good manner. Before you begin, identify all the points that you are going to use. You can discuss in order to establish the point of view and its importance in this argument. For instance, if you are going to discuss something in terms of survival of the fittest, then it will be your task to prove that.The next step is to categorize the general topic of your thesis in terms of the main theme of your essay. If your theme is survival of the fittest, then you have to list out all the things that are related to this theme. You will need to include among others, resources, information and resources which are important for the survival of the fittest. This will give you the basis for your argument.Another idea is to categorize the given topics for a literary analysis essay as strong or weak and based on your capability. The writer of this research paper will be able to talk about various aspects. So, he must be able to provide the information about them. With this, he will be able to clearly discuss what your topic is.However, your ability should be based on your capability and you must take all the necessary details into consideration. Based on the ability you have, you will be able to categorize the given topics for a literary analysis essay as strong or weak. If you are able to do this, you will be in a position to write the content of your article. For the strongest point of view, you can write about the extinction of species or that man is the dominant spe cies.Weak views include the following: I am the dominant species, I am the race or that is wrong. As I said earlier, you can talk about all the details and you will be able to talk about this topic. Now, you can write in the content of your essay. By writing this content, you will be able to make your point. Of course, you must always remember that this is an article. So, you must have a suitable background and knowledge to discuss and write effectively.You can consider the topic as strong or weak. If you want to talk about what you think, then you can categorize the given topics for a literary analysis essay as strong or weak. Just make sure that you go for the weakest one first. Then you can move up to the strongest one. After all, your view will be very important.
