Free charges
However, I can provide you with a general overview of the physics topics that are typically covered in medical entrance exams in India, including AIIMS. These exams usually have a focus on the concepts of Physics that are relevant to the medical field. Some of the important topics are:
- Mechanics: Laws of motion, kinematics, work, energy, power, rotational motion, gravitation, fluids, etc.
- Thermodynamics: Laws of thermodynamics, heat transfer, thermal expansion, kinetic theory of gases, etc.
- Optics: Reflection, refraction, lenses, mirrors, optical instruments, wave optics, etc.
- Electricity and Magnetism: Electric charges, electric fields, capacitors, electric potential, current, resistance, circuits, magnetic fields, electromagnetic induction, AC and DC circuits, etc.
- Modern Physics: Atomic structure, nuclear physics, radioactivity, electronic devices, electromagnetic waves, etc.
It’s important to note that the specific syllabus for AIIMS or any other medical entrance exam can vary, and it’s best to refer to the official syllabus provided by the conducting body or coaching institute for the most accurate and up-to-date information.
Regarding “Free charges,” it seems that you may be referring to the concept of charges in electromagnetism. Free charges are charges that are not bound to any particular atom or molecule and can move freely within a material. They are responsible for the flow of electric current. Electrons are the most common example of free charges in most materials.
What is Required AIIMS-SYLLABUS Physics syllabus Free charges
The AIIMS entrance exam for medical admissions does not have a specific syllabus called “AIIMS-SYLLABUS Physics.” However, I can provide you with a general outline of the physics topics that are typically covered in the AIIMS entrance exam, which may include the concept of free charges:
- Mechanics: Laws of motion, kinematics, work, energy, power, rotational motion, gravitation, fluids, etc.
- Thermodynamics: Laws of thermodynamics, heat transfer, thermal expansion, kinetic theory of gases, etc.
- Optics: Reflection, refraction, lenses, mirrors, optical instruments, wave optics, etc.
- Electricity and Magnetism: Electric charges, electric fields, capacitors, electric potential, current, resistance, circuits, magnetic fields, electromagnetic induction, AC and DC circuits, etc. This is where the concept of free charges may come into play.
- Modern Physics: Atomic structure, nuclear physics, radioactivity, electronic devices, electromagnetic waves, etc.
It’s important to note that the AIIMS entrance exam is primarily focused on the medical sciences, and while physics is a part of the syllabus, it is not as comprehensive as a standalone physics exam. The level of depth and specific topics may vary, and it is recommended to refer to the official AIIMS website or the specific exam notification for the most accurate and up-to-date information on the syllabus.
Case Study on AIIMS-SYLLABUS Physics syllabus Free charges
Electric Conduction in Metals
In the field of physics, the concept of free charges is particularly relevant when studying the behavior of electric currents in metals. Metals are known to be good conductors of electricity due to the presence of free charges.
Consider a simple case where a metal wire is connected to a battery. When the battery is connected and a potential difference is applied across the wire, the free charges within the metal respond to the electric field created by the potential difference.
The free charges in a metal are primarily electrons. These electrons are not bound to any particular atom and are able to move freely within the metal lattice structure. Due to thermal energy, electrons gain kinetic energy and move randomly within the lattice.
When a potential difference is applied across the metal wire, the electric field exerts a force on the free electrons, causing them to move in a directed manner. The electrons flow from the region of higher potential (positive terminal of the battery) to the region of lower potential (negative terminal of the battery).
This movement of free charges constitutes an electric current. The electrons act as charge carriers, transferring charge from one end of the wire to the other. As a result, electrical energy is transported along the wire.
The density of free charges and their mobility determine the conductivity of a metal. Metals with high densities of free charges and high mobility exhibit excellent electrical conductivity. Copper, for example, is commonly used in electrical wiring due to its high conductivity.
In summary, the case study highlights the importance of free charges in the conduction of electricity in metals. Understanding the behavior of free charges is crucial for studying electric currents, circuits, and various electrical phenomena.
Please note that this case study provides a simplified overview of the topic. In reality, the behavior of free charges is more complex and can involve additional factors such as electron scattering, temperature dependence, and the presence of impurities or defects within the metal lattice structure.
