Electrical Resistivity Electrical resistivity, also known as specific electrical resistance, is a fundamental property of a material that quantifies its ability to resist the flow of electric current. It is denoted by the symbol ρ (rho) and is measured in ohm-meters (Ω·m). Resistivity is a material-specific property that helps characterize the behavior of a substance…
Ohms law Ohm’s Law is a fundamental principle in electrical physics that relates the current flowing through a conductor to the voltage across it and the resistance of the conductor. It states that the current (I) flowing through a conductor is directly proportional to the voltage (V) across the conductor and inversely proportional to the…
Mobility The physics syllabus for the Integrated Course at AIIMS (All India Institute of Medical Sciences) covers a wide range of topics. However, since you specifically mentioned mobility, I assume you are referring to the topic of motion and mobility in physics. Here’s an overview of the relevant concepts: These are some of the key…
Velocity Velocity is a fundamental concept in physics that describes the rate of change of an object’s position with respect to time. It is a vector quantity, meaning it has both magnitude and direction. The magnitude of velocity represents the speed at which an object is moving, while the direction indicates the object’s motion in…
Current Electricity Current electricity is a branch of physics that deals with the flow of electric charge in conductive materials. It focuses on the study of electric current, resistance, circuits, and related phenomena. Here are some key concepts and principles related to current electricity: These concepts form the foundation of understanding current electricity and are…
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…
Dipole A dipole is a fundamental concept in physics that refers to a pair of equal and opposite charges or poles separated by a distance. It is commonly encountered in various areas of physics, including electromagnetism and quantum mechanics. Here are some key points about dipoles: These are some of the key aspects of dipoles.…
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…
Superposition principle The superposition principle is a fundamental concept in physics that states that when multiple waves or physical quantities are present in a system, the resultant wave or quantity at any given point is the algebraic sum of the individual waves or quantities. This principle applies to various areas of physics, including classical mechanics,…
Bound charges Bound charges refer to electric charges that are bound within a material and cannot move freely. They are often associated with the polarization of dielectric materials in the presence of an electric field. When an external electric field is applied to a dielectric material, the atoms or molecules in the material can become…
