Class 8 Science Chapter 9 : Ammeter and Voltmeter

Education, অষ্টম শ্রেণি, অষ্টম শ্রেণির বিজ্ঞান, মাধ্যমিক

Today we are going to discuss about Ammeter and Voltmeter: from Class 8 Science Chapter 9 . An ammeter and voltmeter are two important instruments used in electrical engineering and physics to measure the current and voltage in a circuit. They both work by measuring the electrical properties of a circuit and are essential tools for designing, troubleshooting, and repairing electrical systems. Ammeter An ammeter is an instrument used to measure the electric current in a circuit. It is typically connected in series with the circuit and measures the current flowing through it. The unit of measurement for current is the ampere (A), and an ammeter is calibrated in amperes. To measure the current in a circuit using an ammeter, the circuit must be interrupted, and the ammeter must be inserted...

Easy explanation of Ohm’s Law: Class 8 science: Chapter 9

Education, অষ্টম শ্রেণি, অষ্টম শ্রেণির বিজ্ঞান, মাধ্যমিক

Here is an Easy explanation of Ohm's Law: Class 8 science: Chapter 9 Ohm's law is a fundamental principle in electrical engineering and physics. It describes the relationship between voltage, current, and resistance in an electrical circuit. Simply put, Ohm's law states that the current passing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. This article will explain Ohm's law and provide examples and formulas to help you understand it better. The formula for Ohm's law is: V = IR Where V is the voltage, I is the current, and R is the resistance. This formula shows that the voltage across a conductor is directly proportional to the current flowing through it and invers...

Heat energy conversion in chemical reactions : Class 8 Science

Education, অষ্টম শ্রেণি, অষ্টম শ্রেণির বিজ্ঞান, মাধ্যমিক

Heat energy conversion in chemical reactions: Class 8 Science: Chapter 8 Heat energy conversion in chemical reactions is an essential aspect of chemistry. Chemical reactions that involve a change in temperature, whether endothermic or exothermic, can release or absorb heat energy. Heat energy can be converted into other forms of energy such as electrical, mechanical, or sound energy. In this paper, we will discuss heat energy conversion in chemical reactions and provide examples of chemical formulas. Endothermic Reactions Endothermic reactions are those reactions that require the absorption of heat energy to occur. These reactions usually take place in cold environments and are characterized by a decrease in temperature. The heat energy is absorbed by the reactants during the reaction...

Displacement Reaction: Class 8 Science : Chapter 8

Education, অষ্টম শ্রেণি, অষ্টম শ্রেণির বিজ্ঞান, মাধ্যমিক

Displacement Reaction: Class 8 Science: Chapter 8. Discussion on Displacement Reaction. Displacement reactions are a type of chemical reaction in which one element or ion replaces another element or ion in a compound. Displacement reactions occur when a more reactive element displaces a less reactive element from a compound. Displacement reactions are important in many areas of science, including biology, chemistry, and geology. In this paper, we will discuss displacement reactions and provide examples of chemical formulas. The Displacement Reaction The general equation for a displacement reaction is: A + BC → AC + B In this equation, A is the element or ion that is more reactive than B in the compound BC. The more reactive A displaces B from the compound, forming the new compou...
