When an electric current flows through a straight wire, it creates a magnetic field around the wire. This magnetic field is known as the “magnetic field near a current-carrying straight wire.” The magnetic field is perpendicular to the wire and its direction is given by the right-hand rule. If you point your right thumb in…
Ampere’s law is a fundamental law in electromagnetism that relates the magnetic field to the electric current that produces it. It states that the magnetic field around a closed loop is proportional to the electric current passing through the loop. Mathematically, Ampere’s law can be expressed as: ∮B·dl = μ0I where: Ampere’s law is an…
Biot-Savart’s law is a fundamental law in electromagnetism that describes the magnetic field produced by a steady current in a wire. It states that the magnetic field at a point in space due to a current-carrying wire is directly proportional to the current in the wire and the length of the wire segment, and inversely…
The heating effect of current refers to the phenomenon of electrical energy being converted into heat energy when a current flows through a conductor. The amount of heat produced is directly proportional to the square of the current, the resistance of the conductor, and the time for which the current flows. This effect is commonly…
There are countless simple applications that can be developed depending on the platform and programming language used. Here are a few examples: These are just a few examples of simple applications that can be developed. The possibilities are endless, and the complexity of the app will depend on the user’s requirements and the platform they…
Kirchhoff’s laws, also known as Kirchhoff’s circuit laws, are fundamental principles in electrical engineering and physics that describe the behavior of current and voltage in a closed circuit. There are two laws: Mathematically, KCL can be expressed as: Σ I = 0 where Σ I is the sum of all currents flowing into and out…
Cells are the basic unit of life and are the smallest structural and functional unit of living organisms. All living organisms, from the simplest unicellular organisms like bacteria to the most complex multicellular organisms like humans, are made up of cells. Cells have several components, including a cell membrane, cytoplasm, and genetic material. The cell…
When resistors are arranged in parallel, they are connected in such a way that the same voltage is applied across each resistor, and the current is divided among the resistors. The total resistance of the parallel circuit is less than the value of the smallest resistor in the circuit. The current flowing through each resistor…
A series is a sequence of numbers, usually written as a sum of terms. Each term is obtained by applying a rule or formula to the previous term or terms in the series. There are different types of series, such as arithmetic series, geometric series, harmonic series, and more. The properties and behavior of a…
Ohm’s law is a fundamental law of electrical engineering and physics that describes the relationship between electric current, voltage, and resistance in a conductor. It states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. Mathematically,…
