Circuit Analysis Lesson Plan: What is a Circuit? Before we can properly analyse a circuit, we must first understand what a circuit is. A circuit is a closed loop that allows charges to move continuously. There are two requirements that must be met in order to create a circuit: it must be a closed loop with conductive wires connecting to both the positive terminal and negative terminal of the cell, and there must be a source of energy that can increase the electrical potential energy of the charge. Throughout this unit, we have learned about 2 different types of circuits: series and parallel. There are several differences between a series circuit and a parallel circuit, the main one being that a series circuit only has one path for the flow of electricity compared to a parallel circuit which has more than one path for the charges to flow.

Determine the total current of your circuit. Show your work. 4) Which of the following statements is true: A) Adding more resistors to a parallel circuit causes the current to decrease. B) Adding more resistors to a parallel circuit has no effect on the current of the circuit. C) Adding more resistors to a parallel circuit causes the current to increase. D) None of the above are true Solutions: C) Is the correct answer. I mentioned above how when there is less resistance, the current is freer to move around, and since adding resistors to a parallel circuit reduces its total resistance, it also increases its current as well. 5) Which if the below statements is true: A) The voltage of V5 is greater than the voltage of V4. B) The voltage of V4 and V5 is
Electricity is an interesting subject. There is so much you can learn from it, like how our lights turn on or how we make cell phones. This is all a mystery until we finally get a little bit of information in our brains. I've just read two articles, "Energy Story" and "Conducting solutions". I also watched a video called Hands-on Science with Squishy circuits. I learned so much valuable information from these resources.
It was also possible to simulate ED system after the electric resistances of the equivalent circuit were obtained from the analysis of the time course of PaCl. The simulation results agreed with ED data very well.
Students will apply their knowledge of attraction and repulsion between electric charges when testing electrical cells and responding to reflection questions.
...ories, and equations that were introduced in the math chapter in which I struggled, were used in that lab. I was able to see how we can collect data presented by a graph and turn it into an equation and vice versa which in turn will help me to decide the capacity of the electrical source that I need to accomplish a certain operation.
A battery is a device which converts chemical energy into electrical energy. A battery usually consists of two or more cells connected in series or parallel, you can also have a single cell battery. All cells consist of a positive electrode, and a negative electrode. An electrolyte is a liquid substance capable of conducting electricity. In this substance one of the electrodes will react producing electrons, while the other will except electrons. When the electrodes are connected to a device to be powered, called a load, an electrical current flows.
The only problem with this experiment is that when the current passing through the battery circuit was at a continual rate there was...
Electricity and electrical components are a major part of our lives today. Our lives pretty much come to a halt if there is a power outage or if our electrical devices stop working, sometimes we even start panicking because we are so dependent on these components that we cannot afford to lose them and their importance and use only increases as time passes. We all use these electrical devices and also electricity itself but most of us do not think about the math and physics that works behind all of these things.
In a way, capacitors are like batteries. Although they work in completely different ways, capacitors and batteries both store electrical energy in the form of electrons. The difference between a capacitor and a battery is that a capacitor can use its entire charge in a fraction of
AC and DC literally stand for Alternating Current and Direct Current. Direct Current is very convenient and is used in many modern day utilities. For a circuit with DC the current is constanly in one direction, while the voltage remains constant. This makes for a simplistic circuit, for example a flashlight, The batteries are a source of electrochemical DC power and . However AC is called Alternating Current because the voltage changes from negative to positive a given number of times a second, this is also described as the frequency of the power. An example of this would be a motor ran by a hand crank. The inversing of charges creates a sinusoidal graph which looks something like figure 1 (given in radians). This makes for an unsteady power source and can often times be warped from the sinusoidal shape. So the main difference between AC and DC is the way the energy is transmitted.
A battery is a device that converts energy into electricity by storing electrical energy thru chemical reactions. In a battery, there are three major components [4]. The first component of a battery is a terminal called anode which is an electrode through which electric current flows into [2]. The second component of a battery is a terminal is called cathode which is an electrode through which electric current flows out [2]. These two terminals can be found at each end of a battery. The third component of a battery is called the electrolyte which is an ionic compound(s) that are used to separate these two terminals, send electrons and used to neutralize charges that build-up in the chemical reaction processes [2].
All useful generators of electricity come in two basic forms, alternating current and direct current. Direct current (dc) comes from generators that do not change in polarity, always producing a positive charge. In alternating current (ac) the polarity of the terminals is always changing from positive to negative. Thus you are left with alternating current flow. There are different ways of measuring and generating alternating and direct current.
Taking into account the students’ background, I developed this lesson to help them comprehend the targeted grammatical features (gerunds and infinitives) and make them able to use those features in communication with others. The students, as mentioned in the lesson plan, take this class in the evening, which means that they most likely work during the day and probably need to communicate using the language in their work settings. Therefore, it is important to give as many opportunities as possible for the students to use the targeted features in interactive activities, such as interviews and group works. I expect these activities to not only promote negotiation of meaning that is useful for language learning (Long, 1996), but also push them to produce comprehensible output, which also facilitates learning (Swain, 1993).
As an engineering student, design, develop and test electrical equipments is the major purpose of all time. In other words, electrical engineer is concerned with using electricity to transmit electric power. In electrical engineering, there are extensive subfields such as power engineering, control system and signal processing. It is also worth to point out the difference between electrical engineering and electronic engineering. According to the research, electronic engineering is a major that deal with the electronic system such as computers and radar, to be more specific, electronic engineers are concerned with using electricity to process information.
In the process of completing this coursework, I have realised that every teacher should be all-rounded and equipped with adequate skills of educating others as well as self-learning. As a future educator, we need make sure that our knowledge is always up-to-date and applicable in the process of teaching and learning from time to time. With these skills, we will be able to improvise and improve the lesson and therefore boost the competency of pupils in the process of learning. In the process of planning a lesson, I have changed my perception on lesson planning from the student’s desk to the teacher’s desk. I have taken the responsibility as a teacher to plan a whole 60-minutes lesson with my group members. This coursework has given me an opportunity
