Ampere’s Law Ampere’s Law is a fundamental principle in electromagnetism that relates the magnetic field to the electric current flowing through a closed loop. It was formulated by the French physicist André-Marie Ampère. Ampere’s Law states that the line integral of the magnetic field, denoted as B, around a closed path, known as an Amperian…
Magnetic field The magnetic field is a fundamental concept in physics that describes the region surrounding a magnet or a current-carrying conductor where magnetic forces are exerted on other magnets, moving charges, or current-carrying conductors. Key points about the magnetic field include: Understanding the magnetic field and its effects is crucial in various areas, including…
Temperature Dependence Temperature dependence refers to the variation or change in a physical property or phenomenon with temperature. It is a fundamental concept in physics and plays a crucial role in understanding the behavior of different substances and systems. The temperature dependence of a property can be described by mathematical relationships or laws that quantify…
Ohms law Ohm’s Law is a fundamental principle in physics and electrical engineering that describes the relationship between voltage, current, and resistance in an electrical circuit. It states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor. Mathematically, Ohm’s…
Velocity Velocity is a physical quantity that describes the rate of change of an object’s position. It is a vector quantity, meaning it has both magnitude and direction. Velocity is defined as the displacement of an object divided by the time taken to cover that displacement. In equation form, velocity (v) can be expressed as:…
Electric current Electric current refers to the flow of electric charge in a conductor. It is the rate at which electric charges, typically electrons, move through a circuit. The flow of current is driven by a potential difference or voltage applied across the circuit. Electric current is measured in units called amperes (A), named after…
Continuous charge distribution Continuous charge distribution refers to a situation in which electric charge is spread out continuously over a region rather than being concentrated at specific points. It can be described mathematically using charge density, which represents the amount of charge per unit volume, per unit area, or per unit length depending on the…
Insulators Insulators are materials that do not conduct electric current easily. Unlike conductors, which allow the flow of electric charges, insulators resist the movement of electrons. This property makes insulators useful for electrical insulation and preventing the loss of electrical energy. Here are some key points about insulators: Overall, insulators play a crucial role in…
Conductors Conductors are materials that allow the flow of electric charges. They have low resistance to the flow of electrical current. Here are some key points about conductors: It’s important to note that not all materials are conductors. Insulators, for example, have high resistance and do not allow the flow of electric charges. Semiconductors, on…
Electric field Electric field is a fundamental concept in physics that describes the influence of electric charges on other charges or objects in their vicinity. It is a vector field that represents the force experienced by a positive test charge placed at a particular point in space. Key points about electric field: These points provide…
