An investigation is carried out into the control techniques implemented on a tandem linear direct current machine. The purpose is to control the both motions of the conducting bar such that it moves extremely quickly at the reference velocity of 3.7m/s from the beginning of the rail track to the end of the rail track while bringing itself to a halt at a specific displacement. Standard state variable feedback with pole placement was implemented for controller design to obtain the desired performance specifications and compared with basic linear quadratic control. Simulations conducted revealed that the system dynamics that were set were successfully achieved however there is room for improvement and suggestions for future work is provided. The report concludes that standard pole placement feedback produced better results than linear quadratic control due to the nature of the system.

What is reactance? In electricity, measure of the opposition that a circuit or a part of a circuit presents to electric current insofar as the current is varying or alternating is called reactance. Greater reactance gives smaller current for the same applied voltage. Reactance is similar to resistance in this respect, but differs in that reactance does not lead to dissipation of electrical energy as heat. Instead, energy is stored in the reactance, and a quarter-cycle later returned to the circuit, whereas a resistance continuously loses energy. The reactance is to change in any current, not just AC.

Οι μαθητές έχουν τις δικές τους ιδέες σε σχέση με το πώς λειτουργούν τα ηλεκτρικά κυκλώματα. Η χρήση του Νόμου του Ωμ είναι ένας τρόπος για να αναπαρασταθεί η σχέση μεταξύ ρεύματος, τάσης και αντίστασης, όπου σε συνδυασμό με τις ΤΠΕ έρχεται να συμπληρώσει την εκπαιδευτική διαδικασία. Η επιτυχία στο να λύνει κάποιος ποσοτικά προβλήματα χρησιμοποιώντας τον νόμο του Ωμ δεν είναι ένας αξιόπιστος τρόπος για να μετρηθεί η εννοιολογική κατανόηση του θέματος. Στη συγκεκριμένη εργασία μελετάται ο νόμος του Ωμ μέσα από το εικονικό εργαστήριο Tinkercad Circuits, ενώ παράλληλα ερευνάται αρχικά το γνωστικό επίπεδο των μαθητών. Η παρουσίαση του σεναρίου ακολουθεί τη διερευνητική προσέγγιση και περιλαμβάνει πέντε κύριες φάσεις, αυτές της εμπλοκής‐προσανατολισμού, της εννοιολόγησης και αναγνώρισης της πρότερης γνώσης, της έρευνας, της ερμηνείας των αποτελεσμάτων και της συζήτησης. Η αποτίμηση που πραγματοποιήθηκε, έδειξε ότι υπήρξε καθολική αποδοχή του τρόπου με τον οποίο έγινε το μάθημα και ότι όλοι (100%) απόκτησαν καινούργια γνώση σχετικά με το νόμο του Ωμ.

This report discusses the lab experiments about applying both of Ohm’s and Kirchhoff's laws. The main objectives of the experiment were concern about calculating the resistance and currents in the multiple possible methods which were the color coding system, Ohm’s and Kirchoff’s law in a simple resistive network. Five different tasks have been performed in order to achieve to the objectives and discuss the results. Multiple methods were applied in this lab experiment to detect the values of resistance of many circuits. It’s noticeable that measurements and calculations showed results with very low error percentages.

Com base na teoria da primeira lei de Ohm, foi realizado um experimento na qual visa em associar os resistores e conseguir o resultado desejado na saída para confirmar suas propriedades, foi observado também uma maneira de dividir a corrente para que se chegue a um valor especifico de acordo com o procedimento experimental, os resultados obtidos nos experimentos foram base para percebermos que não só a teoria da lei de Ohm é importante como também os divisores de tensão, e chegamos a um consenso em que essa lei se confirma.

- Resistor, Ohm's Law

The growing concern for safety and infrastructural proliferations in the densely populated urban and suburban areas as well as the quest to preserve the aesthetic values in many modern localities have necessitated the need for underground installations. The underground cabling installations are devoid of faults common to the overhead transmission lines but are associated with certain kinds of faults such as short circuit and open circuit faults. Locating the exact position of any of these kinds of faults is very exhausting, costly and time-consuming because its power distribution system is invisible. Hence, a microcontroller based underground cable fault distance locator powered by Arduino is designed to detect and pinpoint location of faults in underground cable lines. A basic ohm’s law is employed to achieve the variation of current with respect to resistance that determines the position of the fault. This device has a power supply unit, cable unit, control unit, tripping unit and display unit. The power supply unit provides power to the other components. The cable unit consists of a three-phase cabling system with switches between each phase to activate faults. The control unit takes in signals from the cable unit to cause control of tripping unit and display unit. The tripping unit then detects the phase which encounters the fault and the display unit shows the fault characteristics on the LCD. The distance to the fault is displayed, alongside the phase which encounters the fault for easy clearance.

The aim of this lab is to be familiar with the devices which are needed in this experiment and to understand how to use them and the function of each device. For example, NI ELVIS Board is used to build an electric circuit by using resistors, wires and power source and those are the components of the simple electric circuits. Also, The Digital Multimeter which is used to measure the values of basic concepts in any circuit such that the resistance, current and voltage which will help us later to understand some laws that are related to it such as Ohm’s law and Kirchhoff’s law.

Аннотация В статье рассматривается формула закона Георга Ома, данная им в его редакции. Его формула описывает величину электроэнергии, пропускаемую проводником при прохождении электричества через него, в зависимости от его свойств. В статье поднимается вопрос о целесообразности возвращения к первоначальной формуле закона Ома, т.к. она яснее и адекватнее отражает содержание процесса прохождения электроэнергии по цепи (участку цепи). Показывается, что при измерении величины электроэнергии в единицах энергии, упрощается описание и понимание закономерности, описанной Омом, электрических процессов в целом.
Abstract
The article considers the formula of the law of George Ohm, given to in its original version. Its formula describes the amount of electricity transmitted by a conductor when electricity passes through it, depending on its properties. The article discusses the feasibility of returning to the original formula of Ohm's law, because it more clearly and adequately reflects the content of the process of the passage of electricity through the circuit (section of the circuit). It is shown that when measuring the amount of electricity in units of energy, the description and understanding of the regularity described by Ohm, of electrical processes as a whole, is simplified.
