Einstein’s photoelectric equation Einstein’s photoelectric equation, also known as the photoelectric effect equation, describes the relationship between the energy of a photon and the maximum kinetic energy of an emitted electron during the photoelectric effect. The equation is as follows: E = hf – φ Where: The photoelectric effect is the phenomenon where electrons are…
Refraction of light Refraction of light is the phenomenon where light waves change direction as they pass from one transparent medium to another due to a change in their speed. It occurs because light waves travel at different speeds in different media, and when they encounter a boundary between two media, their path gets bent.…
AC Generator An AC generator, also known as an alternator, is a device that converts mechanical energy into electrical energy. It is commonly used in power plants, vehicles, and various other applications to generate alternating current (AC). Here are some key points about AC generators: Principle of Operation: Construction: Working: Slip Rings and Brushes: Applications:…
Ferromagnetic devices Ferromagnetic devices are electronic devices or components that utilize the magnetic properties of ferromagnetic materials to perform various functions. These materials exhibit a strong response to magnetic fields and can be magnetized to create a permanent magnet. Here are some examples of ferromagnetic devices: These are just a few examples of ferromagnetic devices.…
Current loop as a magnetic dipole A current loop can be considered as a magnetic dipole due to its magnetic properties. When electric current flows through a closed loop, it generates a magnetic field around it, similar to a bar magnet. This magnetic field is responsible for the loop’s behavior as a magnetic dipole. Here…
Ampere’s Law Ampere’s Law is a fundamental principle in electromagnetism that relates the magnetic field around a closed loop to the electric current passing through that loop. It was first formulated by André-Marie Ampère in the early 19th century and is one of the four Maxwell’s equations, which describe the behavior of electric and magnetic…
A System Of Charges A system of charges refers to a collection of multiple point charges in space. The behavior and interactions of these charges are governed by the principles of electrostatics. When studying a system of charges, several concepts come into play: These concepts help in understanding and analyzing the behavior of a system…
Continuous charge distribution Continuous charge distribution refers to a situation where electric charge is distributed continuously over a region rather than being concentrated at discrete points. In contrast to discrete charge distributions, which involve individual charges at specific locations, continuous charge distributions involve a charge density that varies continuously throughout a given region. Continuous charge…
Human physiology Human physiology is the scientific study of the functions and mechanisms of the human body. It involves understanding how different systems and organs work together to maintain homeostasis and support the overall functioning of the body. Here are some key aspects and systems studied in human physiology: These systems and their various components…
Magnetic effects of current and Magnetism Magnetic effects of current and magnetism are fundamental concepts in physics that describe the relationship between electric currents and magnetic fields. Here are the key aspects of magnetic effects of current and magnetism: Understanding the magnetic effects of current and magnetism is crucial in various fields of science and…
