Carbon Resistors Carbon resistors are electronic components commonly used in electrical circuits to provide resistance. They are made of a cylindrical rod of carbon with metal end caps and color-coded bands that indicate their resistance value. Here are some key points about carbon resistors: It’s worth noting that while carbon resistors have been widely used…
Conductivity Conductivity is a physical property that describes the ability of a material to conduct electric current. It is a fundamental concept in physics and is commonly encountered in various fields, including electrical engineering, materials science, and chemistry. Conductivity is usually denoted by the symbol σ (sigma) and is measured in units of Siemens per…
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…
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 specific point in a circuit. Electric current is measured in units of amperes (A). There are two types of electric current: The flow of electric current is driven…
