Internal resistance is a measure of the opposition to the flow of electric current within a cell or battery. It is an important factor in determining the performance and efficiency of a cell, as it can affect the amount of current that can be drawn from the cell and the voltage drop across the cell under load. There are several factors that can influence the internal resistance of a cell, including the material and design of the cell, the temperature, and the age and condition of the cell.
One of the most significant factors that determines the internal resistance of a cell is the material and design of the cell. Different materials and designs can result in different internal resistances, with some materials and designs having lower resistances than others. For example, cells with thin, high-conductivity electrodes and separators tend to have lower internal resistances than cells with thicker, lower-conductivity electrodes and separators. Similarly, cells with larger surface areas and shorter distances between the electrodes tend to have lower internal resistances than cells with smaller surface areas and longer distances between the electrodes.
Another factor that can influence the internal resistance of a cell is temperature. As the temperature of a cell increases, the internal resistance of the cell generally increases as well. This is due to the fact that the movement of electrons within a cell is influenced by temperature, and as the temperature increases, the movement of electrons becomes more difficult and the resistance increases. Conversely, as the temperature of a cell decreases, the internal resistance of the cell generally decreases.
The age and condition of a cell can also affect its internal resistance. As a cell ages, the internal resistance may increase due to degradation of the materials within the cell or the accumulation of impurities. Similarly, if a cell is damaged or subjected to abuse, the internal resistance may increase as a result.
In summary, the internal resistance of a cell depends on several factors, including the material and design of the cell, the temperature, and the age and condition of the cell. By understanding and controlling these factors, it is possible to optimize the performance and efficiency of a cell.

This may raise some concerns regarding the validity and generalisability of the findings. The informed participants include the Orbit TVET College principal Refer to Appendix A , the campus manager of Orbit TVET College, Brits campus Refer to Appendix B , Heads of Departments HODs , senior lecturers, lecturers and the students Refer to Appendix C. The maximum current is called the short circuit current, I S C. To see the relationship of risk factors to the profitability, this paper is utilizing liquidity current ratio , leverage debt to equity ratio and market risk standard deviation. Take out small resistance 1-5 Ω from the resistance box R connected in parallel with the cell. How do you find the internal resistance of an experiment? His suggestions and instructions have served as the major contributor towards the completion of the project. It is because, as we increase the temperature, more electrolyte dissociates and resistance decreases.
Find the internal resistance of the cell. The researcher further reiterated in each letter addressed to all those involved that this was a voluntary exercise and that they could withdraw, with the use of a letter, whenever they wished to. This application makes our proposed system much more efficient than the already developed systems. When the terminal of the cell are also connected to a resistance of 3 o h m the voltmeter reading drop to 1. Step 3 To see the effect of the temperature of electrolyte on internal resistance by keeping other factors constant. The emf of cell decreases with increase in temperature.
Various factors on which the internal resistance of a cell depends
However, Miceli and Near 1984, p. The jockey key should not be rubbed along the wire. Thus , the batteries need to be made more powerful so that their potential can be increased greatly. Stochastic environmental changes which affect bacterial lifestyle traits can hinder phage infection in numerous ways and create heterogeneity in host phenotypes within a population 35 : changes in temperature can affect the rigidity of the host cell membrane, preventing phage infection 36 , and nutrient variability can reduce expres- sion of phage receptors 37—39. When no current flows there is no energy lost by the internal resistance and the terminal p.
Name two factors on which the internal resistance of a cell depends and state how does it depend on the factors stated by you.
Take out the 2000 ohm plug again from the resistance box R. The internal resistance of a cell is inversely proportional to the concentration of the electrolyte. This has a negative value. What factors affect internal resistance of a battery? Ramamoorthy who guided me throughout this project in every possible way on a step by step basis and ensuring that I completed my project with ease. . I hope that this project will prove to be a breeding ground for the next generation of students and will guide them in every possible way. The potential difference remains the same for all the cells connected in parallel but Current flowing through them is different.
On what factors does the internal resistance of a cell depend?
What is the unit for EMF? Internal Resistance of a cell:The opposition offered by the electrolyte of the cell to the flow of electric current through it is called the internal resistance of the cell. Show more 7 Figure 3 also illustrates the effect of polymer solution concentration on the residual resistance coefficient, the higher the polymer solution concentration, the greater the residual resistance coefficient. Also, check relevant diagrams and FAQs related to the Internal resistance of the cell to get an idea about the kind of questions asked in the exam. The effect of the internal resistance is that the voltage supplied by the power supply drops as the current drawn from the power supply is increased. This has restricted its widespread use for estimating internal resistance. If necessary , adjust the rheostat for this purpose. The financial information is obtained from annual report of Maxis Berhad starting from year 2011 to 2015.
What are the factors on which internal resistance of cell depends Class 12 project? [Answered!]
The internal resistance of a cell is directly proportional to the separation between the electrodes. In recent work by Waag et al. The potential difference will be different across each cell and the current will be the same. Many people have contributed in terms of sharing the ideas, guidance and moral support throughout the study. The system is microcontroller based that consists of a GPS and GSM along with the interfacing of all other sensing units which are all located in various places in that bus. The main functions of a gear box is as follow: 6 According to Creswell 2014 , informed consent means the knowing consent of individuals to participate in an exercise of choice, free from any element of fraud, deceit, duress, or similar unfair inducement or manipulation. Theory The internal resistance of a cell is the resistance offered by its electrolyte to the flow of ions.

The terminal of the cell is connected with a wire to make a closed circuit. It should touch the wire gently. Besides that, the study also helped to determine the relationship between the factors that would affect consumer buying behavior towards healthcare products. It is the inherent property of the cell. When the terminals of the cell are also connected to a resistance of 5Ωas shown in the circuit, the voltmeter reading drops to 1. Cell should not be disturbed during experiment. The internal resistance of a cell is inversely proportional to the effective area of the electrodes.
Internal resistance and the flow of current There is a directly proportional relationship between the current and the energy lost by the internal resistance. The paradigm of stress-induced mutagenesis 8 relates the induction of error-prone DNA polymerases PolIV and PolV 22 and the downregulation of repair proteins 25 to the key stationary-phase stress factor RpoS. Initially when K is open, voltmeter reads 2. Electromotive force EMF is equal to the terminal potential difference when no current flows. The additional measurement is the corporate index score, board remuneration, asset size, net profit margin, GDP growth rate, inflation, unemployment rate and exchange rate.
